--------------------------------------
+1. The intermittent failure is unrelated (looking into it separately). Going
to commit this to master and branch-0.9
> TestDagAwareYarnTaskScheduler fails on Hadoop 3

> When scheduler shutdown is called, the AMRMClientAsyncImple serviceStop is
> invoke, which then interrupts the heartbeat thread and then proceeds to join
> on the heartbeat thread. The heartbeat thread continues to run and continues
> to throw NullPointerExceptions. The interrupt doesn't seem to cause the
> thread to be interrupted now in Hadoop 3 (is YARN-5999 to blame or Tez)
