Subject [jira] [Commented] (YARN-2558) Updating ContainerTokenIdentifier#read/write to use ContainerId#getContainerId
Date Tue, 16 Sep 2014 14:23:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14135514#comment-14135514
] 

Jason Lowe commented on YARN-2558:
----------------------------------

I think this will break rolling upgrades for YARN since the new code won't properly parse
an old token nor will old code properly parse a new token.  We really need to fix YARN-668
or every time we touch a token identifier we break backwards compatibility and thus rolling
upgrades.

> We should update ContainerTokenIdentifier#read/write to use {{getContainerId}} instead
of {{getId}} to pass all container information correctly.
