>
> When a job fails the AM hangs during shutdown. A non-daemon thread pool
> executor thread prevents the JVM teardown from completing, and the AM lingers
> on the cluster for the AM expiry interval in the FINISHING state until
> eventually the RM expires it and kills the container. If application limits
> on the queue are relatively low (e.g.: small queue or small cluster) this can
> cause unnecessary delays in resource scheduling on the cluster.
