Jayush Luniya commented on AMBARI-15169:
----------------------------------------
No new test cases required.
> namenode_ha_utils.py returns sometimes Active NNs as emtpy set, and Stand-by
> NN as a set of 2 NNs in multi-homed environment

> Key: AMBARI-15169
> URL: https://issues.apache.org/jira/browse/AMBARI-15169
> Project: Ambari
> Issue Type: Bug
> Components: stacks
> Affects Versions: 2.2.0
> Reporter: Jayush Luniya
> Assignee: Jayush Luniya
> Fix For: 2.2.2
>
> Attachments: AMBARI-15169.2.patch, AMBARI-15169.patch
>
>
> Steps to Reproduce:
> - Setup multi-homed cluster
> - Upgrade from Ambari 1.7 to Ambari-2.0.2
> - Upgrade from Ambari 2.0.2 to Ambari 2.2.0
> - Try starting Hive Server2 and it fails saying no Active NN
> This happens because we optimized to use webhdfs by default instead of hadoop
> jar calls.
> https://issues.apache.org/jira/browse/AMBARI-11347
> Fix:
> Use dfs.namenode.rpc-address property to get the host/ip. This key should be
> an actual ip/host:port
