> While analyzing YARN-4354 I noticed a nodemanager was getting NPEs while processing a
private localizer heartbeat.  I think there's a race where we can cleanup resources for an
application and therefore remove the app local resource tracker just as we are trying to handle
the localizer heartbeat.
