Subject [jira] [Commented] (HADOOP-7557) Make IPC and RPC headers be extensible
Date Tue, 04 Oct 2011 16:32:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13120255#comment-13120255
] 

Doug Cutting commented on HADOOP-7557:
--------------------------------------

I think PB provides little advantage here and complicates specification of a wire protocol.
 I'd hope our long-term plan is to move towards a standard wire protocol, either adopting
an existing standard protocol or developing our own interoperable, well-specified standard.
 The PB file attached is equivalent to defining three string constant keys whose values are
to be interpreted as strings in RFC-822-style headers.  Or these constants might be assigned
numeric values in the protocol specification, as they are in PB, although that might complicate
embedding this protocol in other standard protocols.
