Description

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.
