Daniel Dai commented on PIG-4921:
---------------------------------
Thanks for taking care of shutdown hook with priority. In case of
InterruptedException of a Tez job, do you actually want to call
TezSessionManager.shutdown()? TezLauncher.kill only kill the running job and
may leave idle AM behind.
> 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.
