METRON-942 [NO MERGE UNTIL METRON-777] Rest api and configuration for
Metron parser extensions
## Contributor Comments
METRON-777 introduces metron extensions and metron parser extensions. The
existing parsers have been moved to be packaged and loaded as extensions.
A maven archetype for creating parser extensions has also been created.
What is missing however is the ability to install a parser extension
created outside the metron tree by the archetype into a metron system.
This PR introduces a REST api to accomplish this.
Along with that, this PR introduces a parser extension configuration type,
for zookeeper that serves as a registry for installed extensions
and their default configurations. The idea being that in a follow on
effort, the management UI will create a new 'instance' of a parser type
through cloning, editing and deploying these configurations. The included
configurations are indexing, enrichment, parser, and elasticsearch.
There may be multiple of these configurations, as each parser extension
library can contain more than one parser.
NOTE: the elasticsearch template is NOT deployed to elasticsearch at this
time. Any parser created will still need a separate step for this.
One outstanding question for feedback -> The configuration tracks the
parsers created out of the extension, initially. In the future this list should
have new parsers added to it when they are cloned. This would mean we
would want new rest endpoints to edit the configuration ( most likely api to
add parser to config {name} ) added
This PR is built on top of METRON-777, and should not be merged until
METRON-777 is in, and this branched is rebased on to master.
### USAGE
For usage, I'll cover creating a parser and deploying it... and deleting it
using the rest api.
## Preparation
In order to build the parser, we need to build and install the maven plugin
to build the bundles, as well as the maven archetype itself.
At this time, since they are not published to apache maven, this will be a
requirement.
- Build the bundle plugin
```
cd bundles-maven-plugin && mvn -q install && cd ..
```
- Build the archetype
```
cd metron-maven-archetypes/metron-maven-parser-extension-archetype
mvn install
cd ../..
```
## Create and build a new parser extension
- Make a directory and cd into it
- Create from archetype
```
mvn archetype:generate -DarchetypeCatalog=local
```
- choose the org.apache.metron:metron-maven-parser-extension-archetype
(Apache Maven Parser Extension Archetype for Metron) option
- Fill out the information (information on the parameters is in the
README for the archetype)
- NOTE: at this time, the version must match the metronVersion. Maven
is using version in the parent pom chain, and messing up the plugin dependency
- cd into the created directory and build the parser extension
```
mvn package
```
This will result in the tar.gz being created inside the
{NAME}-parser-assembly project/target directory
## start full_dev
- run vagrant up from metron-deployment/vagrant/full_dev_platform
## add a slot to storm
- log into ambari on http://node1:8080
- add a new slot to the storm config
## Open swagger
- log into ambari on http://node1:8080
- go into the metron service | quicklinks
- start swagger with user | password
## Install your parser
In swagger, using the parser-extension-controller
- drop down the POST method
- use the file selector to select the created .tar.gz
- execute
The extension should now be installed:
- you should be able to use the other GET methods to review the generated
configuration.
- the configuration will have the extensionID to use for the other {name}
operations
- you should be able to view the installed files in
hdfs/apps/metron/patterns/{parsername}, hdfs/apps/metron/extensions_alt_lib/
## Start the parser using rest
Still in swagger
- Use the Kafka Controller and the Storm Controller to create a
{parserName} topic, and start a storm job for {parserName}
- In the storm UI you should see the storm instance for the parser
You should be able to verify using the rest api and the various controllers
that the configurations are there and the topics exist and the storm jobs as
well
## Uninstall your parser
In swagger, using the parser-extension-controller
- drop down the DELETE method
- fill in the name parameter with the extensionID from the config
- exectute
When complete you should see that the kafka topic, storm job, the various
configurations are all gone, along with the patterns and other things from hdfs
Because this is on METRON-777 the changed file list remains huge.
The main changes here are those in the metron-interface directories
As well as those in the metron-common configuration

NAR changes
* new lib , rebrand to bundles from NAR
* port to VFS/FileObject from File based
* ability to set property values
* Rework FileUtils so that you can derive and override
* added initializers to set 'classes' that we care about instead of hard
coding them, still needs defaults
* added components nec. for integration tests ( do not want dep. on
metron-* )
* VFSClassloader for NarClassLoader
* Hdfs based integration test version of unpacknars tests
* HDFS ( filesystem ) based fileutilities to cover for writes to hdfs,
since VFS is currently R/O HDFS
* modified plugin to support configuration of outputs
* use class index not service loader ( both subclass and annotated
supported )
Archetype
* Parser Extension archetyp
* incudes all configuration
* creates tar.gz with bundle and configuration
* class index support ( automatic generation )
Extensions
* new extensions modules
* parser
* archetype built module for each parser type
* support for configuration only parsers with tests
Parsers
* moved all but json, csv, grok to extensions
* Bolt now loads from bundle properties
Deployment
* rpms for parsers
* create extension directories
* ambari initializes zookeeper per parser
* amabri creates hdfs directories
* ISSUE: Writing to hdfs
Rest-API
* only test against parsers in metron-parsers
* still needs integration

dependency
