Subject [jira] Commented: (HADOOP-6572) RPC responses may be out-of-order with respect to SASL
Date Fri, 19 Feb 2010 09:23:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12835663#action_12835663

Hudson commented on HADOOP-6572:

Integrated in Hadoop-Common-trunk-Commit #177 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-Common-trunk-Commit/177/])
    . Makes sure that SASL encryption and push to responder queue for the RPC response happens
atomically. Contributed by Kan Zhang.

> SASL enforces its own message ordering. When RPC server sends its responses back, response
A may be wrapped by SASL before response B but is put on response queue after response B.
This results in RPC client receiving wrapped response B ahead of A. When the received messages
are unwrapped by SASL, SASL complaints the messages are out of order.
