      Description

      When a nodemanager attempts to shutdown cleanly, it's possible for it to appear to hang due to lingering DeletionService threads. This can occur when yarn.nodemanager.delete.debug-delay-sec is set to a relatively large value and one or more containers executes on the node shortly before the shutdown.

      The DeletionService is never calling setExecuteExistingDelayedTasksAfterShutdownPolicy() on the ScheduledThreadPoolExecutor, and it defaults to waiting for all scheduled tasks to complete before exiting.
