+
+---++ Cluster Specification
+The cluster XSD specification is available here:
+A cluster contains different interfaces which are used by Falcon like
readonly, write, workflow and messaging.
+A cluster is referenced by feeds and processes which are on-boarded to Falcon
by its name.
+
+Following are the tags defined in a cluster.xml:
+<verbatim>
+<cluster colo="gs" description="" name="corp" xmlns="uri:falcon:cluster:0.1"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
+</verbatim>
+The colo specifies the colo to which this cluster belongs to and name is the
name of the cluster which has to
+be unique.
+
+
+---+++ Interfaces
+
+A cluster has various interfaces as described below:
+<verbatim>
+ <interface type="readonly" endpoint="hftp://localhost:50010";
version="0.20.2" />
+</verbatim>
+A readonly interface specifies the endpoint for Hadoop's HFTP protocol,
+this would be used in the context of feed replication.
+
+<verbatim>
+<interface type="write" endpoint="hdfs://localhost:8020" version="0.20.2" />
+</verbatim>
+A write interface specifies the interface to write to hdfs, it's endpoint is
the value of fs.defaultFS.
+Falcon uses this interface to write system data to hdfs and feeds referencing
this cluster are written to hdfs
+using the same write interface.
+
+<verbatim>
+<interface type="execute" endpoint="localhost:8021" version="0.20.2" />
+</verbatim>
+An execute interface specifies the interface for job tracker, it's endpoint is
the value of mapreduce.jobtracker.address.
+Falcon uses this interface to submit the processes as jobs on !JobTracker
defined here.
+
+<verbatim>
+<interface type="workflow" endpoint="http://localhost:11000/oozie/";
version="4.0" />
+</verbatim>
+A workflow interface specifies the interface for workflow engine, example of
its endpoint is the value for OOZIE_URL.
+Falcon uses this interface to schedule the processes referencing this cluster
on workflow engine defined here.
+
+<verbatim>
+<interface type="registry" endpoint="thrift://localhost:9083" version="0.11.0"
/>
+</verbatim>
+A registry interface specifies the interface for metadata catalog, such as
Hive Metastore (or HCatalog).
+Falcon uses this interface to register/de-register partitions for a given
database and table. Also,
+uses this information to schedule data availability events based on partitions
in the workflow engine.
+Although Hive metastore supports both RPC and HTTP, Falcon comes with an
implementation for RPC over thrift.
+
+<verbatim>
+<interface type="messaging" endpoint="tcp://localhost:61616?daemon=true"
version="5.4.6" />
+</verbatim>
+A messaging interface specifies the interface for sending feed availability
messages, it's endpoint is broker url with tcp address.
+
+---+++ Locations
+
+A cluster has a list of locations defined:
+<verbatim>
+<location name="staging" path="/projects/falcon/staging" />
+<location name="working" path="/projects/falcon/working" />
+</verbatim>
+Location has the name and the path, name is the type of locations like
staging, temp and working.
+and path is the hdfs path for each location.
+Falcon would use the location to do intermediate processing of entities in
hdfs and hence Falcon
+should have read/write/execute permission on these locations.
+These locations MUST be created prior to submitting a cluster entity to Falcon.
+*staging* must have 777 permissions and the parent dirs must have execute
permissions so multiple
+users can write to this location
+*working* must have 755 permissions and the parent dirs must have execute
permissions so multiple
+users can read from this location
+
+---+++ ACL
+
+A cluster has ACL (Access Control List) useful for implementing permission
requirements
+and provide a way to set different permissions for specific users or named
groups.
+<verbatim>
+ <ACL owner="test-user" group="test-group" permission="*"/>
+</verbatim>
+ACL indicates the Access control list for this cluster.
+owner is the Owner of this entity.
+group is the one which has access to read.
+permission indicates the permission.
+
+---+++ Custom Properties
+
+A cluster has a list of properties:
+A key-value pair, which are propagated to the workflow engine.
+<verbatim>
+<property name="brokerImplClass"
value="org.apache.activemq.ActiveMQConnectionFactory" />
+</verbatim>
+Ideally JMS impl class name of messaging engine (brokerImplClass)
+should be defined here.
+
+---++ Feed Specification
+The Feed XSD specification is available here.
+A Feed defines various attributes of feed like feed location, frequency,
late-arrival handling and retention policies.
+A feed can be scheduled on a cluster, once a feed is scheduled its retention
and replication process are triggered in a given cluster.
+<verbatim>
+<feed description="clicks log" name="clicks" xmlns="uri:falcon:feed:0.1"
+xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
+</verbatim>
+A feed should have a unique name and this name is referenced by processes as
input or output feed.
+
+---+++ Storage
+Falcon introduces a new abstraction to encapsulate the storage for a given
feed which can either be
+expressed as a path on the file system, File System Storage or a table in a
catalog such as Hive, Catalog Storage.
+
+<verbatim>
+ <xs:choice minOccurs="1" maxOccurs="1">
+ <xs:element type="locations" name="locations"/>
+ <xs:element type="catalog-table" name="table"/>
+ </xs:choice>
+</verbatim>
+
+Feed should contain one of the two storage options. Locations on File System
or Table in a Catalog.
+
+---++++ File System Storage
+
+<verbatim>
+ <clusters>
+ <cluster name="test-cluster">
+ <validity start="2012-07-20T03:00Z" end="2099-07-16T00:00Z"/>
+ <retention limit="days(10)" action="delete"/>
+ <sla slaLow="hours(3)" slaHigh="hours(4)"/>
+ <locations>
+ <location type="data"
path="/hdfsDataLocation/${YEAR}/${MONTH}/${DAY}/${HOUR}/${MINUTE}"/>
+ <location type="stats" path="/projects/falcon/clicksStats" />
+ <location type="meta" path="/projects/falcon/clicksMetaData" />
+ </locations>
+ </cluster>
+..... more clusters </clusters>
+</verbatim>
+Feed references a cluster by it's name, before submitting a feed all the
referenced cluster should be submitted to Falcon.
+type: specifies whether the referenced cluster should be treated as a source
or target for a feed. A feed can have multiple source and target clusters. If
the type of cluster is not specified then the cluster is not considered for
replication.
+Validity of a feed on cluster specifies duration for which this feed is valid
on this cluster.
+Retention specifies how long the feed is retained on this cluster and the
action to be taken on the feed after the expiry of retention period.
+The retention limit is specified by expression frequency(times), ex: if feed
should be retained for at least 6 hours then retention's limit="hours(6)".
+The field partitionExp contains partition tags. Number of partition tags has
to be equal to number of partitions specified in feed schema. A partition tag
can be a wildcard(*), a static string or an expression. Atleast one of the
strings has to be an expression.
+sla specifies sla for the feed on this cluster. This is an optional parameter
and sla can be same or different from the
+global sla tag (mentioned outside the clusters tag ). This tag provides the
user to flexibility to have
+different sla for different clusters e.g. in case of replication. If this
attribute is missing then the default global
+sla is picked from the feed definition.
+Location specifies where the feed is available on this cluster. This is an
optional parameter and path can be same or different from the global locations
tag value ( it is mentioned outside the clusters tag ) . This tag provides the
user to flexibility to have feed at different locations on different clusters.
If this attribute is missing then the default global location is picked from
the feed definition. Also the individual location tags data, stats, meta are
optional.
+<verbatim>
+ <location type="data" path="/projects/falcon/clicks" />
+ <location type="stats" path="/projects/falcon/clicksStats" />
+ <location type="meta" path="/projects/falcon/clicksMetaData" />
+</verbatim>
+A location tag specifies the type of location like data, meta, stats and the
corresponding paths for them.
+A feed should at least define the location for type data, which specifies the
HDFS path pattern where the feed is generated
+periodically. ex: type="data"
path="/projects/TrafficHourly/${YEAR}-${MONTH}-${DAY}/traffic"
+The granularity of date pattern in the path should be at least that of a
frequency of a feed.
+Other location type which are supported are stats and meta paths, if a process
references a feed then the meta and stats
+paths are available as a property in a process.
+
+---++++ Catalog Storage (Table)
+
+A table tag specifies the table URI in the catalog registry as:
+<verbatim>
+catalog:$database-name:$table-name#partition-key=partition-value);partition-key=partition-value);*
+</verbatim>
+
+This is modeled as a URI (similar to an ISBN URI). It does not have any
reference to Hive or HCatalog. Its quite
+generic so it can be tied to other implementations of a catalog registry. The
catalog implementation specified
+in the startup config provides implementation for the catalog URI.
+
+Top-level partition has to be a dated pattern and the granularity of date
pattern should be at least that
+of a frequency of a feed.
+
+<verbatim>
+ <xs:complexType name="catalog-table">
+ <xs:annotation>
+ <xs:documentation>
+ catalog specifies the uri of a Hive table along with the
partition spec.
+
uri="catalog:$database:$table#(partition-key=partition-value);+"
+ Example: catalog:logs-db:clicks#ds=${YEAR}-${MONTH}-${DAY}
+ </xs:documentation>
+ </xs:annotation>
+ <xs:attribute type="xs:string" name="uri" use="required"/>
+ </xs:complexType>
+</verbatim>
+
+Examples:
+<verbatim>
+<table
uri="catalog:default:clicks#ds=${YEAR}-${MONTH}-${DAY}-${HOUR};region=${region}"
/>
+<table
uri="catalog:src_demo_db:customer_raw#ds=${YEAR}-${MONTH}-${DAY}-${HOUR}" />
+<table
uri="catalog:tgt_demo_db:customer_bcp#ds=${YEAR}-${MONTH}-${DAY}-${HOUR}" />
+</verbatim>
+
+---+++ Partitions
+
+<verbatim>
+ <partitions>
+ <partition name="country" />
+ <partition name="cluster" />
+ </partitions>
+</verbatim>
+A feed can define multiple partitions, if a referenced cluster defines
partitions then the number of partitions in feed has to be equal to or more
than the cluster partitions.
+
+*Note:* This will only apply for !FileSystem storage but not Table storage as
partitions are defined and maintained in
+Hive (HCatalog) registry.
+
+---+++ Groups
+
+<verbatim>
+ <groups>online,bi</groups>
+</verbatim>
+A feed specifies a list of comma separated groups, a group is a logical
grouping of feeds and a group is said to be
+available if all the feeds belonging to a group are available. The frequency
of all the feed which belong to the same group
+must be same.
+
+---+++ Availability Flags
+
+<verbatim>
+ <availabilityFlag>_SUCCESS</availabilityFlag>
+</verbatim>
+An availabilityFlag specifies the name of a file which when present/created in
a feeds data directory,
+the feed is termed as available. ex: _SUCCESS, if this element is ignored then
Falcon would consider the presence of feed's
+data directory as feed availability.
+
+---+++ Frequency
+
+<verbatim>
+ <frequency>minutes(20)</frequency>
+</verbatim>
+A feed has a frequency which specifies the frequency by which this feed is
generated.
+ex: it can be generated every hour, every 5 minutes, daily, weekly etc.
+valid frequency type for a feed are minutes, hours, days, months. The values
can be negative, zero or positive.
+
+---+++ SLA
+<verbatim>
+ <sla slaLow="hours(40)" slaHigh="hours(44)" />
+</verbatim>
+
+A feed can have SLA and each SLA has two properties - slaLow and slaHigh. Both
slaLow and slaHigh are written using
+expressions like frequency. slaLow is intended to serve for alerting for feed
instances which are in danger of missing their
+availability SLAs. slaHigh is intended to serve for reporting the feeds which
missed their SLAs. SLAs are relative to
+feed instance time.
+
+
+---+++ Late Arrival
+
+<verbatim>
+ <late-arrival cut-off="hours(6)" />
+</verbatim>
+A late-arrival specifies the cut-off period till which the feed is expected to
arrive late and should be honored be processes referring to it as input feed by
rerunning the instances in case the data arrives late with in a cut-off period.
+The cut-off period is specified by expression frequency(times), ex: if the
feed can arrive late
+upto 8 hours then late-arrival's cut-off="hours(8)"
+
+*Note:* This will only apply for !FileSystem storage but not Table storage
until a future time.
+
+---+++ ACL
+
+A feed has ACL (Access Control List) useful for implementing permission
requirements
+and provide a way to set different permissions for specific users or named
groups.
+<verbatim>
+ <ACL owner="test-user" group="test-group" permission="*"/>
+</verbatim>
+ACL indicates the Access control list for this cluster.
+owner is the Owner of this entity.
+group is the one which has access to read.
+permission indicates the permission.
+
+---+++ Custom Properties
+
+<verbatim>
+ <properties>
+ <property name="tmpFeedPath" value="tmpFeedPathValue" />
+ <property name="field2" value="value2" />
+ <property name="queueName" value="hadoopQueue"/>
+ <property name="jobPriority" value="VERY_HIGH"/>
+ <property name="timeout" value="hours(1)"/>
+ <property name="parallel" value="3"/>
+ <property name="maxMaps" value="8"/>
+ <property name="mapBandwidth" value="1"/>
+ </properties>
+</verbatim>
+A key-value pair, which are propagated to the workflow engine. "queueName" and
"jobPriority" are special properties
+available to user to specify the Hadoop job queue and priority, the same value
is used by Falcons launcher job.
+"timeout" and "parallel" are other special properties which decides
replication instance's timeout value while
+waiting for the feed instance and parallel decides the concurrent replication
instances that can run at any given time. "maxMaps" represents the maximum
number of maps used during replication. "mapBandwidth" represents the bandwidth
in MB/s used by each mapper during replication.
+
+---++ Process Specification
+A process defines configuration for a workflow. A workflow is a directed
acyclic graph(DAG) which defines the job for the workflow engine. A process
definition defines the configurations required to run the workflow job. For
example, process defines the frequency at which the workflow should run, the
clusters on which the workflow should run, the inputs and outputs for the
workflow, how the workflow failures should be handled, how the late inputs
should be handled and so on.
+
+The different details of process are:
+---+++ Name
+Each process is identified with a unique name.
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+</process>
+</verbatim>
+
+---+++ Tags
+An optional list of comma separated tags which are used for classification of
processes.
+Syntax:
+<verbatim>
+...
+ <tags>consumer=consu...@xyz.com, owner=produ...@xyz.com,
department=forecasting</tags>
+</verbatim>
+
+---+++ Pipelines
+An optional list of comma separated word strings, specifies the data
processing pipeline(s) to which this process belongs.
+Only letters, numbers and underscore are allowed for pipeline string.
+Syntax:
+<verbatim>
+...
+ <pipelines>test_Pipeline, dataReplication, clickStream_pipeline</pipelines>
+</verbatim>
+
+---+++ Cluster
+The cluster on which the workflow should run. A process should contain one or
more clusters. Cluster definition for the cluster name gives the end points for
workflow execution, name node, job tracker, messaging and so on. Each cluster
inturn has validity mentioned, which tell the times between which the job
should run on that specified cluster.
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <clusters>
+ <cluster name="test-cluster1">
+ <validity start="2012-12-21T08:15Z" end="2100-01-01T00:00Z"/>
+ </cluster>
+ <cluster name="test-cluster2">
+ <validity start="2012-12-21T08:15Z" end="2100-01-01T00:00Z"/>
+ </cluster>
+ ....
+ ....
+ </clusters>
+
+...
+</process>
+</verbatim>
+
+---+++ Parallel
+Parallel defines how many instances of the workflow can run concurrently. It
should be a positive integer > 0.
+For example, parallel of 1 ensures that only one instance of the workflow can
run at a time. The next instance will start only after the running instance
completes.
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <parallel>[parallel]</parallel>
+...
+</process>
+</verbatim>
+
+---+++ Order
+Order defines the order in which the ready instances are picked up. The
possible values are FIFO(First In First Out), LIFO(Last In First Out), and
ONLYLAST(Last Only).
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <order>[order]</order>
+...
+</process>
+</verbatim>
+
+---+++ Timeout
+A optional Timeout specifies the maximum time an instance waits for a dataset
before being killed by the workflow engine, a time out is specified like
frequency.
+If timeout is not specified, falcon computes a default timeout for a process
based on its frequency, which is six times of the frequency of process or 30
minutes if computed timeout is less than 30 minutes.
+<verbatim>
+<process name="[process name]">
+...
+ <timeout>[timeunit]([frequency])</timeout>
+...
+</process>
+</verbatim>
+
+---+++ Frequency
+Frequency defines how frequently the workflow job should run. For example,
hours(1) defines the frequency as hourly, days(7) defines weekly frequency. The
values for timeunit can be minutes/hours/days/months and the frequency number
should be a positive integer > 0.
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <frequency>[timeunit]([frequency])</order>
+...
+</process>
+</verbatim>
+
+---+++ SLA
+<verbatim>
+ <sla shouldStartIn="hours(2)" shouldEndIn="hours(4)"/>
+</verbatim>
+A process can have SLA which is defined by 2 optional attributes -
shouldStartIn and shouldEndIn. All the attributes
+are written using expressions like frequency. shouldStartIn is the time by
which the process should have started.
+shouldEndIn is the time by which the process should have finished.
+
+
+---+++ Validity
+Validity defines how long the workflow should run. It has 3 components - start
time, end time and timezone. Start time and end time are timestamps defined in
yyyy-MM-dd'T'HH:mm'Z' format and should always be in UTC. Timezone is used to
compute the next instances starting from start time. The workflow will start at
start time and end before end time specified on a given cluster. So, there will
not be a workflow instance at end time.
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <validity start=[start time] end=[end time] timezone=[timezone]/>
+...
+</process>
+</verbatim>
+
+Examples:
+<verbatim>
+<process name="sample-process">
+...
+ <frequency>days(1)</frequency>
+ <validity start="2012-01-01T00:40Z" end="2012-04-01T00:00" timezone="UTC"/>
+...
+</process>
+</verbatim>
+The daily workflow will start on Jan 1st 2012 at 00:40 UTC, it will run at
40th minute of every hour and the last instance will be at March 31st 2012 at
23:40 UTC.
+
+<verbatim>
+<process name="sample-process">
+...
+ <frequency>hours(1)</frequency>
+ <validity start="2012-03-11T08:40Z" end="2012-03-12T08:00"
timezone="PST8PDT"/>
+...
+</process>
+</verbatim>
+The hourly workflow will start on March 11th 2012 at 00:40 PST, the next
instances will be at 01:40 PST, 03:40 PDT, 04:40 PDT and so on till 23:40 PDT.
So, there will be just 23 instances of the workflow for March 11th 2012 because
of DST switch.
+
+---+++ Inputs
+Inputs define the input data for the workflow. The workflow job will start
executing only after the schedule time and when all the inputs are available.
There can be 0 or more inputs and each of the input maps to a feed. The path
and frequency of input data is picked up from feed definition. Each input
should also define start and end instances in terms of
[[FalconDocumentation][EL expressions]] and can optionally specify specific
partition of input that the workflow requires. The components in partition
should be subset of partitions defined in the feed.
+
+For each input, Falcon will create a property with the input name that
contains the comma separated list of input paths. This property can be used in
workflow actions like pig scripts and so on.
+
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <inputs>
+ <input name=[input name] feed=[feed name] start=[start el] end=[end
el] partition=[partition]/>
+ ...
+ </inputs>
+...
+</process>
+</verbatim>
+
+Example:
+<verbatim>
+<feed name="feed1">
+...
+ <partition name="isFraud"/>
+ <partition name="country"/>
+ <frequency>hours(1)</frequency>
+ <locations>
+ <location type="data"

+<process name="sample-process">
+...
+ <inputs>
+ <input name="input1" feed="feed1" start="today(0,0)" end="today(1,0)"
partition="*/US"/>
+ ...
+ </inputs>
+...
+</process>
+</verbatim>
+The input for the workflow is a hourly feed and takes 0th and 1st hour data of
today(the day when the workflow runs).
+If the workflow is running for 2012-03-01T06:40Z, the inputs are
/projects/bootcamp/feed1/2012-03-01-00/*/US and
+/projects/bootcamp/feed1/2012-03-01-01/*/US. The property for this input is
+input1=/projects/bootcamp/feed1/2012-03-01-00/*/US,/projects/bootcamp/feed1/2012-03-01-01/*/US
+
+Also, feeds with Hive table storage can be used as inputs to a process.
Several parameters from inputs are passed as
+params to the user workflow or pig script.
+
+<verbatim>
+ ${wf:conf('falcon_input_database')} - database name associated with the
feed for a given input
+ ${wf:conf('falcon_input_table')} - table name associated with the feed for
a given input
+ ${wf:conf('falcon_input_catalog_url')} - Hive metastore URI for this input
feed

${coord:dataInPartitionFilter('$input', 'hive')}
+ ${wf:conf('falcon_input_partition_filter_java')} - value of
${coord:dataInPartitionFilter('$input', 'java')}
+</verbatim>
+
+*NOTE:* input is the name of the input configured in the process, which is
input.getName().
+<verbatim><input name="input" feed="clicks-raw-table" start="yesterday(0,0)"
end="yesterday(20,0)"/></verbatim>

+</configuration>
+</verbatim>
+
+
+---+++ Optional Inputs
+User can mention one or more inputs as optional inputs. In such cases the job
does not wait on those inputs which are
+mentioned as optional. If they are present it considers them otherwise
continue with the compulsory ones.
+Example:
+<verbatim>
+<feed name="feed1">
+...
+ <partition name="isFraud"/>
+ <partition name="country"/>
+ <frequency>hours(1)</frequency>
+ <locations>
+ <location type="data"

partition="*/UK" optional="true" />
+ ...
+ </inputs>
+...
+</process>
+</verbatim>
+
+*Note:* This is only supported for !FileSystem storage but not Table storage
at this point.
+
+
+---+++ Outputs
+Outputs define the output data that is generated by the workflow. A process
can define 0 or more outputs. Each output is mapped to a feed and the output
path is picked up from feed definition. The output instance that should be
generated is specified in terms of [[FalconDocumentation][EL expression]].
+
+For each output, Falcon creates a property with output name that contains the
path of output data. This can be used in workflows to store in the path.
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <outputs>
+ <output name=[input name] feed=[feed name] instance=[instance el]/>
+ ...
+ </outputs>
+...

+<process name="sample-process">
+...
+ <outputs>
+ <output name="output1" feed="feed2" instance="today(0,0)"/>
+ ...
+ </outputs>
+...
+</process>
+</verbatim>
+The output of the workflow is feed instance for today. If the workflow is
running for 2012-03-01T06:40Z,
+the workflow generates output /projects/bootcamp/feed2/2012-03-01. The
property for this output that is available
+for workflow is: output1=/projects/bootcamp/feed2/2012-03-01
+
+Also, feeds with Hive table storage can be used as outputs to a process.
Several parameters from outputs are passed as
+params to the user workflow or pig script.
+<verbatim>
+ ${wf:conf('falcon_output_database')} - database name associated with the
feed for a given output
+ ${wf:conf('falcon_output_table')} - table name associated with the feed
for a given output

output feed
+ ${wf:conf('falcon_output_dataout_partitions')} - value of
${coord:dataOutPartitions('$output')}
+</verbatim>
+
+*NOTE:* output is the name of the output configured in the process, which is
output.getName().

+The properties are key value pairs that are passed to the workflow. These
properties are optional and can be used
+in workflow to parameterize the workflow.

which can be used to propagate to pig or M/R job.
+<verbatim>
+ <property name="queueName" value="hadoopQueue"/>
+ <property name="jobPriority" value="VERY_HIGH"/>
+</verbatim>
+
+---+++ Workflow
+
+The workflow defines the workflow engine that should be used and the path to
the workflow on hdfs.
+The workflow definition on hdfs contains the actual job that should run and it
should confirm to
+the workflow specification of the engine specified. The libraries required by
the workflow should
+be in lib folder inside the workflow path.
+
+The properties defined in the cluster and cluster properties(nameNode and
jobTracker) will also
+be available for the workflow.
+
+There are 2 engines supported today.
+
+---++++ Oozie
+
+As part of oozie workflow engine support, users can embed a oozie workflow.
+Refer to oozie [[http://oozie.apache.org/docs/4.0.1/DG_Overview.html][workflow
overview]] and
+[[http://oozie.apache.org/docs/4.0.1/WorkflowFunctionalSpec.html][workflow
specification]] for details.
+
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <workflow engine=[workflow engine] path=[workflow path]/>
+...
+</process>
+</verbatim>
+
+Example:
+<verbatim>
+<process name="sample-process">
+...
+ <workflow engine="oozie" path="/projects/bootcamp/workflow"/>
+...
+</process>
+</verbatim>
+
+This defines the workflow engine to be oozie and the workflow xml is defined at
+/projects/bootcamp/workflow/workflow.xml. The libraries are at
/projects/bootcamp/workflow/lib.
+
+---++++ Pig
+
+Falcon also adds the Pig engine which enables users to embed a Pig script as a
process.
+
+Example:
+<verbatim>
+<process name="sample-process">
+...
+ <workflow engine="pig" path="/projects/bootcamp/pig.script"/>
+...
+</process>
+</verbatim>
+
+This defines the workflow engine to be pig and the pig script is defined at
+/projects/bootcamp/pig.script.
+
+Feeds with Hive table storage will send one more parameter apart from the
general ones:
+<verbatim>$input_filter</verbatim>
+
+---++++ Hive
+
+Falcon also adds the Hive engine as part of Hive Integration which enables
users to embed a Hive script as a process.
+This would enable users to create materialized queries in a declarative way.
+
+Example:
+<verbatim>
+<process name="sample-process">
+...
+ <workflow engine="hive" path="/projects/bootcamp/hive-script.hql"/>
+...
+</process>
+</verbatim>
+
+This defines the workflow engine to be hive and the hive script is defined at
+/projects/bootcamp/hive-script.hql.
+
+Feeds with Hive table storage will send one more parameter apart from the
general ones:
+<verbatim>$input_filter</verbatim>
+
+---+++ Retry
+Retry policy defines how the workflow failures should be handled. Two retry
policies are defined: backoff and exp-backoff(exponential backoff). Depending
on the delay and number of attempts, the workflow is re-tried after specific
intervals.
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <retry policy=[retry policy] delay=[retry delay] attempts=[retry
attempts]/>
+...
+</process>
+</verbatim>
+
+Examples:
+<verbatim>
+<process name="sample-process">
+...
+ <retry policy="backoff" delay="minutes(10)" attempts="3"/>
+...
+</process>
+</verbatim>
+The workflow is re-tried after 10 mins, 20 mins and 30 mins. With exponential
backoff, the workflow will be re-tried after 10 mins, 20 mins and 40 mins.
+
+---+++ Late data
+Late data handling defines how the late data should be handled. Each feed is
defined with a late cut-off value which specifies the time till which late data
is valid. For example, late cut-off of hours(6) means that data for nth hour
can get delayed by upto 6 hours. Late data specification in process defines how
this late data is handled.
+
+Late data policy defines how frequently check is done to detect late data. The
policies supported are: backoff, exp-backoff(exponention backoff) and final(at
feed's late cut-off). The policy along with delay defines the interval at which
late data check is done.
+
+Late input specification for each input defines the workflow that should run
when late data is detected for that input.
+
+Syntax:
+<verbatim>
+<process name="[process name]">
+...
+ <late-process policy=[late handling policy] delay=[delay]>
+ <late-input input=[input name] workflow-path=[workflow path]/>
+ ...
+ </late-process>
+...
+</process>
+</verbatim>
+
+Example:
+<verbatim>
+<feed name="feed1">
+...
+ <frequency>hours(1)</frequency>
+ <late-arrival cut-off="hours(6)"/>
+...
+</feed>
+<process name="sample-process">
+...
+ <inputs>
+ <input name="input1" feed="feed1" start="today(0,0)" end="today(1,0)"/>
+ ...
+ </inputs>
+ <late-process policy="final">
+ <late-input input="input1"
workflow-path="/projects/bootcamp/workflow/lateinput1" />
+ ...
+ </late-process>
+...
+</process>
+</verbatim>
+This late handling specifies that late data detection should run at feed's
late cut-off which is 6 hours in this case. If there is late data, Falcon
should run the workflow specified at
/projects/bootcamp/workflow/lateinput1/workflow.xml
+
+*Note:* This is only supported for !FileSystem storage but not Table storage
at this point.
+
+---+++ ACL
+
+A process has ACL (Access Control List) useful for implementing permission
requirements
+and provide a way to set different permissions for specific users or named
groups.
+<verbatim>
+ <ACL owner="test-user" group="test-group" permission="*"/>
+</verbatim>
+ACL indicates the Access control list for this cluster.
+owner is the Owner of this entity.
+group is the one which has access to read.
+permission indicates the permission.

+---+FalconCLI
+
+FalconCLI is a interface between user and Falcon. It is a command line utility
provided by Falcon. FalconCLI supports Entity Management, Instance Management
and Admin operations.There is a set of web services that are used by FalconCLI
to interact with Falcon.
+
+---++Entity Management Operations
+
+---+++Submit
+
+Submit option is used to set up entity definition.
+
+Example:
+$FALCON_HOME/bin/falcon entity -submit -type cluster -file
/cluster/definition.xml
+
+Note: The url option in the above and all subsequent commands is optional. If
not mentioned it will be picked from client.properties file. If the option is
not provided and also not set in client.properties, Falcon CLI will fail.
+
+---+++Schedule
+
+Once submitted, an entity can be scheduled using schedule option. Process and
feed can only be scheduled.
+
+Usage:
+$FALCON_HOME/bin/falcon entity -type [process|feed] -name <<name>> -schedule
+
+Example:
+$FALCON_HOME/bin/falcon entity -type process -name sampleProcess -schedule
+
+---+++Suspend
+
+Suspend on an entity results in suspension of the oozie bundle that was
scheduled earlier through the schedule function. No further instances are
executed on a suspended entity. Only schedule-able entities(process/feed) can
be suspended.
+
+Usage:
+$FALCON_HOME/bin/falcon entity -type [feed|process] -name <<name>> -suspend
+
+---+++Resume
+
+Puts a suspended process/feed back to active, which in turn resumes applicable
oozie bundle.
+
+Usage:
+ $FALCON_HOME/bin/falcon entity -type [feed|process] -name <<name>> -resume
+
+---+++Delete
+
+Delete removes the submitted entity definition for the specified entity and
put it into the archive.
+
+Usage:
+$FALCON_HOME/bin/falcon entity -type [cluster|feed|process] -name <<name>>
-delete
+
+---+++List
+
+Entities of a particular type can be listed with list sub-command.

+
+<a href="./Restapi/EntitySummary.html">Optional params described here.</a>
+
+---+++Update
+
+Update operation allows an already submitted/scheduled entity to be updated.
Cluster update is currently
+not allowed.
+
+Usage:

+
+---+++Dependency
+
+With the use of dependency option, we can list all the entities on which the
specified entity is dependent. For example for a feed, dependency return the
cluster name and for process it returns all the input feeds, output feeds and
cluster names.
+
+Usage:
+$FALCON_HOME/bin/falcon entity -type [cluster|feed|process] -name <<name>>
-dependency
+
+---+++Definition
+
+Definition option returns the entity definition submitted earlier during
submit step.
+
+Usage:
+$FALCON_HOME/bin/falcon entity -type [cluster|feed|process] -name <<name>>
-definition
+
+---++Instance Management Options
+
+---+++Kill
+
+Kill sub-command is used to kill all the instances of the specified process
whose nominal time is between the given start time and end time.
+
+Note:
+1. The start time and end time needs to be specified in TZ format.
+Example: 01 Jan 2012 01:00 => 2012-01-01T01:00Z
+
+3. Process name is compulsory parameter for each instance management command.
+
+Usage:
+$FALCON_HOME/bin/falcon instance -type <<feed/process>> -name <<name>> -kill
-start "yyyy-MM-dd'T'HH:mm'Z'" -end "yyyy-MM-dd'T'HH:mm'Z'"
+
+---+++Suspend
+
+Suspend is used to suspend a instance or instances for the given process.
This option pauses the parent workflow at the state, which it was in at the
time of execution of this command.
+
+Usage:
+$FALCON_HOME/bin/falcon instance -type <<feed/process>> -name <<name>>
-suspend -start "yyyy-MM-dd'T'HH:mm'Z'" -end "yyyy-MM-dd'T'HH:mm'Z'"
+
+---+++Continue
+
+Continue option is used to continue the failed workflow instance. This option
is valid only for process instances in terminal state, i.e. KILLED or FAILED.
+
+Usage:
+$FALCON_HOME/bin/falcon instance -type <<feed/process>> -name <<name>>
-continue -start "yyyy-MM-dd'T'HH:mm'Z'" -end "yyyy-MM-dd'T'HH:mm'Z'"
+
+---+++Rerun
+
+Rerun option is used to rerun instances of a given process. This option is
valid only for process instances in terminal state, i.e. SUCCEDDED, KILLED or
FAILED. Optionally, you can specify the properties to override.
+
+Usage:
+$FALCON_HOME/bin/falcon instance -type <<feed/process>> -name <<name>> -rerun
-start "yyyy-MM-dd'T'HH:mm'Z'" -end "yyyy-MM-dd'T'HH:mm'Z'" [-file <<properties
file>>]
+
+---+++Resume
+
+Resume option is used to resume any instance that is in suspended state.
+
+Usage:
+$FALCON_HOME/bin/falcon instance -type <<feed/process>> -name <<name>> -resume
-start "yyyy-MM-dd'T'HH:mm'Z'" -end "yyyy-MM-dd'T'HH:mm'Z'"
+
+---+++Status
+
+Status option via CLI can be used to get the status of a single or multiple
instances. If the instance is not yet materialized but is within the process
validity range, WAITING is returned as the state. Along with the status of the
instance time is also returned. Log location gives the oozie workflow url
+If the instance is in WAITING state, missing dependencies are listed.
+The job urls are populated for all actions of user workflow and non-succeeded
actions of the main-workflow. The user then need not go to the underlying
scheduler to get the job urls when needed to debug an issue in the job.
+
+Example : Suppose a process has 3 instance, one has succeeded,one is in
running state and other one is waiting, the expected output is:
+
+{"status":"SUCCEEDED","message":"getStatus is
successful","instances":[{"instance":"2012-05-07T05:02Z","status":"SUCCEEDED","logFile":"http://oozie-dashboard-url"},{"instance":"2012-05-07T05:07Z","status":"RUNNING","logFile":"http://oozie-dashboard-url"},
