> Job rerun is divided into two commands.
> 1. ReRunXCommand, which delete action and set job status to prep.
> 2. StartXCommand, which start WF.
> If ReRunXCommand fails to acquire job lock, it's requeued and oozie will start StartXCommand command. ReRunXCommand will run again ( after/parallel to StartXCommand) when it can acquire lock.
> {code}
