Tom White commented on MAPREDUCE-3837:
--------------------------------------
Mayank - thanks for pointing that out. I just tried and they fail for me on the
latest branch-1 code too. We do need tests for job tracker recovery though, so
they should be fixed to ensure that the code in this patch is tested and
doesn't regress, don't you think?
> Hadoop 22 Job tracker is not able to recover job in case of crash and after
> that no user can submit job.

> 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.
