Subject [jira] [Commented] (HDFS-2181) Seperate HDFS wire protocol data types
Date Wed, 05 Oct 2011 23:46:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2181?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13121603#comment-13121603

Todd Lipcon commented on HDFS-2181:

Hi Sanjay. One question:

bq. As we add new types in future releases, the protocol version will NOT change (recall the
rule - add new types and new methods)

Is that still true, after this feature? I thought that, with this new protocol selection feature,
we would simply duplicate the "protocolR23" package to "protocolR24" when R24 was released,
etc? So we only had to worry about method/field compatibility within a release, but between
releases, we could change the wire format as we liked?
