Subject [jira] [Commented] (HADOOP-7776) Make the Ipc-Header in a RPC-Payload an explicit header
Date Tue, 01 Nov 2011 17:25:32 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13141356#comment-13141356

Doug Cutting commented on HADOOP-7776:

Sanjay, yes, I agree that extensibility can be added later by changing the version number.
 Such a change would not be forward compatible.  Once extensibility is added then forward-compatible
changes to per-request metadata will be possible, but perhaps that's not your goal at this

It seemed to me that, as long as you're re-writing the code that processes headers, and you
intend to rewrite it again soon to make it extensible (HADOOP-7557) then we might combine
these two steps in order to avoid debugging code that we'll soon discard.  But if you'd prefer
to implement these steps sequentially that's fine too.  Or do I misunderstand the relationship
between this and HADOOP-7557?
