> Wrongly configured 'hadoop.job.history.user.location' can disable job-history. Jobs retires
when JobHistory notifies the JobTracker after moving the history file to the done folder (i.e
mapreduce.jobtracker.jobhistory.completed.location). If the JobHistory gets disabled, JobTracker
would not receive any notification and thus jobs will be pinned in JobTracker's memory forever.
