Subject [jira] [Commented] (HADOOP-7227) Remove protocol version check at proxy creation in Hadoop RPC.
Date Tue, 03 May 2011 17:15:03 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13028320#comment-13028320

Jitendra Nath Pandey commented on HADOOP-7227:

I ran hdfs tests and mr tests with this patch in common.

hdfs: All tests pass except TestHdfsTrash, TestReplaceDatanodeOnFailure, TestMetaSave which
failed for unrelated reasons

mr: All tests passed except TestMiniMRChildTask which also failed for unrelated reason.

> 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.
