Daniel Dai commented on PIG-4921:
---------------------------------
It kills active session but not idle sessions. Idle session will go away when
expire, so probably no big deal. But when you say HangingJobKiller duplicates
TezSessionManager.shutdown, it's not true, TezSessionManager.shutdown does more
than HangingJobKiller.
> Kill running jobs on InterruptedException

> Shutdown hook kills running jobs, but when running in Oozie launcher
> sometimes NodeManager can issue a SIGKILL after AM unregisters and before
> shutdown hook gets to execute causing orphaned jobs that continue to run. So
> it is better to kill when we see the InterruptedException.
> Added additional System.err logging to code in shutdown hooks as
> LogManager.shutdown() is called by mapreduce AM (Oozie launcher job is
> mapreduce) and log4j logging does not appear anymore.
