> 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.
