>                 URL: https://issues.apache.org/jira/browse/AMBARI-22361
>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-agent
>    Affects Versions: 2.6.0
>         Environment: HDFS/2.1.0.2.0
>            Reporter: stephanesan
>            Priority: Normal
>
> Error at hand:
> Connection failed to http://vz-sl-upupup-8724-hadoop-mgr-1:0 (<urlopen error [Errno 111] Connection refused>)
> Explanation:
> In the command json file the hostname is in lower case, while in HA mode the
> hdfs-site property dfs.namenode.http-address.{{ha-nameservice}}.{{nn_id}}
> may
> have upper case parts, which prevents matching the hostname.
> Proposal:
> Apply similar patch as done for https://issues.apache.org/jira/browse/AMBARI-19282
