> 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.
