Ning Zhang commented on HIVE-1349:
----------------------------------
Can you add the new hive parameter to conf/hive-default.xml as well? Other than
that it looks good.
> Do not pull counters of non initialized jobs

>
> Right now hive client puts a lot of pressure on the jobtracker by pulling the
> counters of the job that has just been submitted and is in the process of
> initializing tasks.
> While the job initialized tasks and reads the splits file it is holding the
> JobInProgress lock. The getCounters method acquires a JobTracker lock and
> waits for the JobInProgress lock. Since the read of the file can take a
> couple (a couple of tens of seconds) the job tracker is effectively blocked
> for that period of time.
