> 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.
