Subject [jira] [Commented] (HADOOP-9421) Convert SASL to use ProtoBuf and add lengths for non-blocking processing
Date Fri, 21 Jun 2013 01:39:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13689952#comment-13689952

Benoy Antony commented on HADOOP-9421:
--------------------------------------

Luke, Is there a sufficient need to add a new state REINITIATE ? The only benefit is that
it avoids a isSupportedInitiate() call.

>From what I understood, Luke's change is a desirable optimization of Daryn's protocol.
Such optimization is quite common in protocols. I agree that it complicates the design a bit.
Tt may never be used with the subsequent changes related to IP Failover etc, but why not keep
it there as it should not cause any impact on performance?  Why would it cause change in performance
?
