> Currently, both SHUTDOWN event from nodeStatusUpdater and CleanupContainers
> event happens to be on the same dispatcher thread, CleanupContainers Event
> will not be processed until SHUTDOWN event is processed. see similar problem
> on YARN-495.
> On normal NM shutdown, this is not a problem since normal stop happens on
> shutdownHook thread.
