[jira] [Commented] (YARN-669) ContainerTokens sent from the RM to NM via the AM should be a byte field

    [ https://issues.apache.org/jira/browse/YARN-669?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13657224#comment-13657224 ] 

Siddharth Seth commented on YARN-669:
-------------------------------------

Was this changed recently. I was under the impression that the MR AM was reading some of the fields from this container. IAC, in the current state this jira can be closed.

> AMs should not try to read any information from this Token, since this token is used as an authorization mechanism. Converting it to a byte field also allows changes to the token.
> This could be considered part of the API jira - YARN-386.
