> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.7.0
> Reporter: mujunchao

> 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.
