Subject [jira] [Commented] (HADOOP-9421) Convert SASL to use ProtoBuf and add lengths for non-blocking processing
Date Fri, 21 Jun 2013 19:40:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13690638#comment-13690638
] 

Daryn Sharp commented on HADOOP-9421:
-------------------------------------

We agreed that guessing wasn't going to be implemented.  There's no penalty for token auth
because of my other optimization.  Kerberos takes a tiny penalty but it's necessary to support
subsequent IP failover changes.

My existing SASL unit tests exercise the full matrix of client and server auths, both with
and without tokens.  Writing tests all the way down to the wire is going to further delay
this patch.  I think Arun is pretty eager to get this in.  If we want wire tests, then I think
we should defer to another jira and get 2.1 unblocked.
