    Description

      When the ApplicationMaster encounters an invalid state transition in one of its many state machines (JobImpl, TaskImpl, TaskAttemptImpl, etc.) the job will fail with the ERROR state but the diagnostics string doesn't have any information about the failure. The diagnostics string should contain a message indicating the job is failing because of an invalid state transition and, preferably, details on the nature of the internal error.
