Subject [jira] [Assigned] (YARN-669) ContainerTokens sent from the RM to NM via the AM should be a byte field
Date Mon, 13 May 2013 21:13:16 GMT

     [ https://issues.apache.org/jira/browse/YARN-669?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli reassigned YARN-669:
--------------------------------------------

    Assignee: Vinod Kumar Vavilapalli

As I noted elsewhere, ContainerToken is already only exposing ByteBuffers for the identifier
and the password. Do we need to do more?

> 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.
