--------------------------------------

[~jlowe], do you have any insights into who is at fault for the hang in this jira? YARN? TEZ?

> 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)
