Bugs: OOZIE-1584
https://issues.apache.org/jira/browse/OOZIE-1584
Repository: oozie
Description
-------
Supported features.
-----------------
1. If Oozie.action.ship.launcher.jar = true then, Oozie auto-deploy jar at
server start.
2. Admin copies sharelib to new timestamp directory and issues invalidate
command to Oozie server. Oozie picks latest shared lib.
3. Oozie server doesn't auto deploy sharelib at startup. It picks the latest
sharelib jar pushed by admin(based on timestamp).
4. Sharelib mapping files.
Sharelib mapping file can be also configured.Configured file is a key value
mapping, where key will be the action and value is DFS directory of sharelib
files for action.
This can be configured in oozie-site.xml as :
<property>
<name>oozie.service.ShareLibService.mapping.file</name>
<value></value>
<description>
Sharelib mapping files contains list of key=value,
where key is the action key and value is the DFS location of
sharelib files.
</description>
</property>

DFS after generating launcher jar by ooozie server and sharelib by cli

Purging.
-------------
There are two set( launcher_ for launcher jars and Lib_ for shared lib) of
directory and purging happens for both at startup.
Anything older than ( defined in property) is purged.
We always keep 2 set of directory, purging happens if number of sharelib
directory > 2.
Multiple version.
-------------------
To support multiple version, sharelib will be in below format.
Sharelib will cache all versions and return list of dfs files for a particular
version.
