[jira] [Updated] (OOZIE-1584) Setup sharelib using script and
pickup latest(honor ship.launcher) and remove DFS dependency at startup.
[ https://issues.apache.org/jira/browse/OOZIE-1584?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
purshotam shah updated OOZIE-1584:
----------------------------------
Description:
Supported features.
1. If Oozie.action.ship.launcher.jar = true then, Oozie auto-deploy jar at server starts.
2. Admin copies sharelib to new timestamp directory(using sharelibCLI) and issues invalidate command(using oozieCLI) 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).
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.
