Subject [jira] [Commented] (YARN-3208) RM-AM connection should be reauthorized when token changes
Date Tue, 17 Feb 2015 21:27:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-3208?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14324916#comment-14324916

Jason Lowe commented on YARN-3208:

Ideally this could be done over the existing AM-RM connection if the IPC layer were extend
to support it.  Otherwise we would need one side to shut down the connection and force the
AM to reconnect to the RM and re-authenticate.

tokens and successfully hands a new token to the AM.
