Subject [jira] [Commented] (HADOOP-9698) RPCv9 client must honor server's SASL negotiate response
Date Thu, 18 Jul 2013 16:56:48 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13712484#comment-13712484

Daryn Sharp commented on HADOOP-9698:
-------------------------------------

Branch-2 patch just needs -F3 fuzz for 1 hunk.  I won't post it yet to avoid having a pre-commit
fail.  

I've manually retested with all combinations of simple/kerberos + clients/servers.  Also verified
the client gets angry if the server advertised principal doesn't exactly match the principal
in the conf, and fallback to simple flag works.

> As of HADOOP-9421, a RPCv9 server will advertise its authentication methods.  This is
meant to support features such as IP failover, better token selection, and interoperability
in a heterogenous security environment.
> Currently the client ignores the negotiate response and just blindly attempts to authenticate
instead of choosing a mutually agreeable auth method.
