> 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,
> Mayank
