the log directory of the JobTracker 
-------------------------------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-2714
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2714
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.20.2, 0.20.1
            Reporter: Liyin Liang
            Assignee: Liyin Liang


After MAPREDUCE-130, the job's conf copy will be deleted from the log directory of the JobTracker
when the job is retired. However, it just works if the job is retired by _RetireJobs_ thread
of JobTracker. If a job is retired by the same user's another job, its conf copy will not
be deleted. This kind of retire happens in _JobTracker::finalizeJob(job)_, when JobTracker
maintains more than _MAX_COMPLETE_USER_JOBS_IN_MEMORY_ jobs information in memory for a given
user.
