---------------------------------
Summary: Disallow self-failover when auto failover is enabled
Key: HDFS-3713
URL: https://issues.apache.org/jira/browse/HDFS-3713
Project: Hadoop HDFS
Issue Type: Bug
Components: auto-failover
Affects Versions: 2.0.0-alpha
Reporter: Eli Collins
Priority: Minor
When auto failover is enabled, the user can manually failover from a
nameservice to itself. When auto failover is disabled, there is a check that
prevents failover from a nameservice to itself, we should have the same check
for auto failover.
