>
> 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: Blocker
> Attachments: HADOOP-9698.patch, HADOOP-9698.patch, RPCv9
> Authentication.pdf
>
>
> 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.
