[jira] [Created] (YARN-668) TokenIdentifier serialization should consider Unknown fields

Siddharth Seth created YARN-668:
-----------------------------------

             Summary: TokenIdentifier serialization should consider Unknown fields
                 Key: YARN-668
                 URL: https://issues.apache.org/jira/browse/YARN-668
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Siddharth Seth


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.
