[jira] [Created] (HDFS-6334) Client failover proxy provider for IP failover based NN HA

Kihwal Lee created HDFS-6334:
--------------------------------

             Summary: Client failover proxy provider for IP failover based NN HA
                 Key: HDFS-6334
                 URL: https://issues.apache.org/jira/browse/HDFS-6334
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Kihwal Lee
            Assignee: Kihwal Lee


With RPCv9 and improvements in the SPNEGO auth handling, it is possible to set up a pair of HA namenodes utilizing IP failover as client-request fencing mechanism.

This jira will make it possible for HA to be configured without requiring use of logical URI and provide a simple IP failover proxy provider.  The change will allow any old implementation of {{FailoverProxyProvider}} to continue to work.
