Subject [jira] Commented: (HADOOP-6596) Should add version to the serialization of DelegationToken
Date Wed, 24 Feb 2010 19:51:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6596?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12837980#action_12837980

Owen O'Malley commented on HADOOP-6596:
---------------------------------------

Jeff, my point was that I am trying to put a serialized copy of the delegation token in a
http request. Including a full-blown avro schema in a http request would be overkill. The
context here is that I'm trying to pass along a delegation token in a http request. Since
this will be used for hftp, enabling compatibility between versions is required and therefore
I need versioning support. Going to thrift or protobufs seems like overkill for this, so I'm
proposing adding a version byte that will let us change the serialization later.

> Now that we are adding the serialized form of delegation tokens into the http interfaces,
we should include some version information.
