When an application is unregistered there is a chance that there are still containers running on a node for that application. In all cases we handle the application missing from the RM gracefully (log a message and continue) except for the FS pre-emption thread.
In case the application is removed but some containers are still linked to a node the FSPreemptionThread will crash with a NPE when it tries to retrieve the application id for the attempt:
FSAppAttempt app = scheduler.getSchedulerApp(container.getApplicationAttemptId()); ApplicationId appId = app.getApplicationId();
