[jira] [Commented] (HADOOP-9698) RPCv9 client must honor server's SASL negotiate response

    [ https://issues.apache.org/jira/browse/HADOOP-9698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13699221#comment-13699221 ] 

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

I would like to elevate this to blocker since the required changes will break earlier RPCv9 clients in some cases.  I plan to have a patch available before monday.

> 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.
