    Description

      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.
