Hadoop 22 Job tracker is not able to recover job in case of crash and after that no user can
submit job.
--------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-3837
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3837
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.22.0
            Reporter: Mayank Bansal
            Assignee: Mayank Bansal


If job tracker is crashed while running , and there were some jobs are running , so if job
tracker's property mapreduce.jobtracker.restart.recover is true then it should recover the
job.

However the current behavior is as follows
jobtracker try to restore the jobs but it can not . And after that jobtracker closes it handle
to hdfs and nobody else also can not submit the job. 

Thanks,
Mayank
