All, I tried to enabled HDFS NameNode HA with Ambari 2.1 and HDP 2.3, I failed to enable this, I did some search, the error I have is different from this issue, https://issues.apache.org/jira/browse/AMBARI-12374, but the error message I got is similar, is this a known issue? Seems some code causing active NameNode address can not be retrieved? Any issue to track this? Is there a hot fix on this? thanks
