----------------------------------------
Patch available at: https://github.com/tucu00/oozie/commits/AOOZIE-9
> Launcher job should be able to run in different queue than job itself
> ---------------------------------------------------------------------
>
> Key: OOZIE-9
> URL: https://issues.apache.org/jira/browse/OOZIE-9
> Project: Apache Oozie (Incubating)
> Issue Type: Bug
> Reporter: Alejandro Abdelnur
> Assignee: Alejandro Abdelnur
>
> Currently, if not queue or a custom queue is set for an action, the launcher
> job will use the same queue.
> This leads to a deadlock situation in small clusters where all slots are
> taken by launcher jobs that cannot progress because there are not slots avail.
> The solution is to allow launchers to use a different queue (i.e.
> oozie.launcher.mapred.job.queue.name=launcherqueue).
> This can be done today, but if the action defines a custom queue (i.e.
> mapred.job.queue.name=fooqueue) the above property is overwritten and both
> launcher and job end up in the same queue.
> The JavaActionExecutor should do a special check.
