Jian He commented on YARN-1116:
-------------------------------
Looks like simply populating the password inside AMRMToken back to
AMRMTokenSecretManager after RM restarts is enough.

> The AMRMTokens are now only saved in RMStateStore and not populated back to

> AMRMToken also becomes used in non-secure env.
