    Description

      The RM on one of our clusters was running behind on processing AsyncDispatcher events, and this caused AMs to fail to register due to an NPE. The AM was launched and attempting to register before the RMAppAttemptImpl had processed the LAUNCHED event, and the client to AM token had not been generated yet. The NPE occurred because the ApplicationMasterService tried to encode the missing token.
