Tom White commented on MAPREDUCE-3837:
--------------------------------------
+1 to the fix. FWIW I didn't see this when testing on a single-node cluster (on
Mac OS X).
> Job tracker is not able to recover job in case of crash and after that no
> user can submit job.

> 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 its handle to hdfs and nobody else can submit job.
> Thanks,
