> Currently when the ApplicationMaster unregisters with the ResourceManager, the RM kills (via the NMs) all the active containers for an application. This introduces a race where the AM may be trying to clean up and may not finish before it is killed. The RM should give the AM a chance to exit cleanly on its own rather than always race with a pending kill on shutdown.
