Alejandro Abdelnur commented on OOZIE-1461:
-------------------------------------------
why do we need #3? I think this is not necessary. If you want a performance
boost just use #2. If you are using sharelibs, you can just set the config for
#2 and it will work, nothing additional to do.
> provide an option to auto-deploy launcher jar onto HDFS system libpath

>
> after OOZIE-1311, 1315, when oozie.action.ship.launcher.jar is false,
> launcher jar is shipped from sharelib, but it requires manual process for
> admin people to upload jar files onto the sharelib at server-start time,
> before actually starting running workflow actions. This JIRA to provide an
> option to remove the manual process, and make oozie server (ActionService) to
> automatically create and upload launcher jar files onto HDFS (tmp directory
> under oozie.service.WorkflowAppService.system.libpath), and allow workflow
> actions to consume from there. every time oozie server starts, it
> automatically creates a new directory to upload launcher jars to, and also
> purges stale directories previously created (older than 7 days,
> configurable).
> if false (which is current default). the behavior is the same with previous,
> launcher jars provided from sharelib (when
> oozie.action.ship.launcher.jar=false) or each workflow action creates and
> ships launcher jar (when oozie.action.ship.launcher.jar=true)
