Rohini Palaniswamy commented on OOZIE-1461:
-------------------------------------------
bq. Currently, the sharelib is only replaced if the admin goes and does it
manually, or if the admin goes and runs the oozie-setup.sh command to
upload/upgrade the sharelib; the only time this should be needed is when the
jars in the sharelib need to be updated.
Our admins certainly will not like running a separate script every time they
do installation but not when they do settings change and restart. Human
operations are prone to errors and if they forget to run the script for a
release it becomes a problem. Even if it is not per restart, every patch
release will require a replacement of the sharelib and all the jobs that were
running during that time will fail.

> 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)
