2 (if directory though exists can not be written to)
will update
> CompletedJobStatusStore initialization should fail if

> If {mapred.job.tracker.persist.jobstatus.dir} points to an unwritable
> location or mkdir of {mapred.job.tracker.persist.jobstatus.dir} fails, then
> CompletedJobStatusStore silently ignores the failure and disables
> CompletedJobStatusStore. Ideally the JobTracker should bail out early
> indicating a misconfiguration.
