> 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.
