Siddharth Seth commented on HIVE-16820:
---------------------------------------
Sorry for the delay.
- Should isShutdown be volatile for visibility outside of the dagLock
synchronized block?
- Think it is possible for two invocations of tryKillDag. submitDag sets
this.dagClient. shutdown sees this, and invokes tryKillDag. the submit thread
starts up again and sees isShutdown=true.
Otherwise, looks good.
> TezTask may not shut down correctly before submit
