--------------------------------
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.
