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.
