> The check for max-completed-jobs-per-user is made in finalize job and hence there can
be a case where the user finishes more than 'mapred.jobtracker.completeuserjobs.maximum' jobs
within  JobTracker.MIN_TIME_BEFORE_RETIRE units of time and doesnt submit any job after that
which can cause more number of jobs to be in memory than allowed. There is no check made for
this limit anywhere else.
