Subject [jira] [Commented] (YARN-668) TokenIdentifier serialization should consider Unknown fields
Date Thu, 18 Sep 2014 23:37:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14139731#comment-14139731

Vinod Kumar Vavilapalli commented on YARN-668:
----------------------------------------------

One more thing. Let's version each of the token separately and validate the versions on the
NodeManager during startContainer() to catch incompatible changes. The Token is redesigned
anyways, so we can start with version 0.

> This would allow changing of the TokenIdentifier between versions. The current serialization
is Writable. A simple way to achieve this would be to have a Proto object as the payload for
TokenIdentifiers, instead of individual fields.
> TokenIdentifier continues to implement Writable to work with the RPC layer - but the
payload itself is serialized using PB.
