      Description

      We register the ClientTokenMasterKey to avoid client may hold an invalid ClientToken after RM restarts. In SIMPLE mode, we register Pair<ApplicationAttemptId, null> , But we never remove it from HashMap, as unregister only runing while in Security mode, so memory leak coming.
