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

Daryn Sharp created HADOOP-9698:
-----------------------------------

             Summary: RPCv9 client must honor server's SASL negotiate response
                 Key: HADOOP-9698
                 URL: https://issues.apache.org/jira/browse/HADOOP-9698
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: ipc
    Affects Versions: 3.0.0, 2.1.0-beta
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp
            Priority: Critical


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.
