Jason Lowe commented on YARN-1978:
----------------------------------
Is calling sched.awaitTermination(10, SECONDS) without ever calling
sched.shutdown() or sched.shutdownNow() equivalent to Thread.sleep(10*1000)?
I'm wondering if this change is going to always cause the NM to take 10 seconds
to shutdown which isn't ideal.
