Subject [jira] [Created] (HADOOP-7227) Remove protocol version check at proxy creation in Hadoop RPC.
Date Fri, 15 Apr 2011 00:36:06 GMT
Remove protocol version check at proxy creation in Hadoop RPC.
--------------------------------------------------------------

                 Key: HADOOP-7227
                 URL: https://issues.apache.org/jira/browse/HADOOP-7227
             Project: Hadoop Common
          Issue Type: New Feature
            Reporter: Jitendra Nath Pandey
            Assignee: Jitendra Nath Pandey


Currently when a proxy is created for a protocol, there is a round trip of messages to check
the protocol version. The protocol version is not checked in any subsequent rpc which could
be a problem if the server restarts with a new protocol version. This issue and also the additional
round-trip at proxy creation can be avoided if we add the protocol version in every rpc, and
server checks the protocol version for every call.
