[jira] [Commented] (YARN-1116) Populate AMRMTokens back to AMRMTokenSecretManager after RM restarts

    [ https://issues.apache.org/jira/browse/YARN-1116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13755278#comment-13755278 ] 

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 AMRMTokenSecretManager after RM restarts. This is more needed now since AMRMToken also becomes used in non-secure env.
