> Key: HDFS-6334
> URL: https://issues.apache.org/jira/browse/HDFS-6334
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Kihwal Lee
> Assignee: Kihwal Lee
> Fix For: 3.0.0, 2.5.0
>
> Attachments: HDFS-6334.patch, HDFS-6334.v2.patch, HDFS-6334.v3.patch
>
>
> 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.
