> The job staging directory is deleted in the job cleanup task, which happens
> before the job-info file is deleted from the system directory (by the
> JobInProgress garbageCollect() method). If the JT shuts down between these
> two operations, then when the JT restarts and tries to recover the job, it
> fails since the job.xml and splits are no longer available.
