Devaraj K commented on YARN-3857:

Thanks [~mujunchao] for reporting and working in this. I am assigning this issue to you.

Adding to [~zxu], Can you also take care of the naming convention for the patch like <JIRA-ID>-<patch-version>.patch?

>  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.
