-Oozie, Yahoo Workflow Engine for Hadoop.
+Apache Oozie
+=============
-PLEASE NOTE:
+What is Oozie
+--------------
- * Yahoo! does not offer any support for the
- Yahoo! Distribution of Oozie.
+Oozie is an extensible, scalable and reliable system to define, manage,
schedule, and execute complex Hadoop workloads via web services. More
specifically, this includes:
- * This distribution includes cryptographic software that
- is subject to U.S. export control laws and applicable
- export and import laws of other countries. BEFORE using
- any software made available from this site, it is your
- responsibility to understand and comply with these laws.
- This software is being exported in accordance with the
- Export Administration Regulations. As of June 2009, you
- are prohibited from exporting and re-exporting this
- software to Cuba, Iran, North Korea, Sudan, Syria and
- any other countries specified by regulatory update to
- the U.S. export control laws and regulations. Diversion
- contrary to U.S. law is prohibited.
+ * XML-based declarative framework to specify a job or a complex workflow of
dependent jobs.
+ * Support different types of job such as Hadoop Map-Reduce, Pipe, Streaming,
Pig, Hive and custom java applications.
+ * Workflow scheduling based on frequency and/or data availability.
+ * Monitoring capability, automatic retry and failure handing of jobs.
+ * Extensible and pluggable architecture to allow arbitrary grid programming
paradigms.
+ * Authentication, authorization, and capacity-aware load throttling to allow
multi-tenant software as a service.

-Oozie Documentation:
+Oozie Overview
+----------
- http://yahoo.github.com/oozie/releases/3.0.0
+Oozie is a server based Workflow Engine specialized in running workflow jobs
with actions that run Hadoop Map/Reduce and Pig jobs.
-Oozie Quick Start:
+Oozie is a Java Web-Application that runs in a Java servlet-container.
+
+For the purposes of Oozie, a workflow is a collection of actions (i.e. Hadoop
Map/Reduce jobs, Pig jobs) arranged in a control dependency DAG (Direct Acyclic
Graph). "control dependency" from one action to another means that the second
action can't run until the first action has completed.
+
+Oozie workflows definitions are written in hPDL (a XML Process Definition
Language similar to JBOSS JBPM jPDL).
+
+Oozie workflow actions start jobs in remote systems (i.e. Hadoop, Pig). Upon
action completion, the remote systems callback Oozie to notify the action
completion, at this point Oozie proceeds to the next action in the workflow.
+
+Oozie workflows contain control flow nodes and action nodes.
+
+Control flow nodes define the beginning and the end of a workflow ( start ,
end and fail nodes) and provide a mechanism to control the workflow execution
path ( decision , fork and join nodes).
- http://yahoo.github.com/oozie/releases/3.0.0/DG_QuickStart.html
+Action nodes are the mechanism by which a workflow triggers the execution of a
computation/processing task. Oozie provides support for different types of
actions: Hadoop map-reduce, Hadoop file system, Pig, SSH, HTTP, eMail and Oozie
sub-workflow. Oozie can be extended to support additional type of actions.
-Oozie Detailed Installation and Configuration:
+Oozie workflows can be parameterized (using variables like ${inputDir} within
the workflow definition). When submitting a workflow job values for the
parameters must be provided. If properly parameterized (i.e. using different
output directories) several identical workflow jobs can concurrently.

+Documentations :
+-----------------
+Oozie web service is bundle with the built-in details documentation.
-Building Oozie:
+More inforamtion could be found at:

+
+Supported Hadoop Versions:
+----------------------------
+
+This version of Oozie was primarily tested aganist Hadoop 0.20.205.x. Other
earlier version (0.20.x) should work as well. However, it was not tested
aganist 0.23+ yet.
