[~elek] thanks for reporting this. OM behavior is also same. Rpc Server is binded to socket
address returned by {{OmUtils.getOmAddress}}.

>             Project: Hadoop Distributed Data Store
>          Issue Type: Bug
>    Affects Versions: 0.4.0
>            Reporter: Elek, Marton
>            Assignee: Ajay Kumar
>            Priority: Major

> In the "*.kerberos.principal" settings hadoop supports the _HOST variable which is replaced
to the fully qualified domain name.
> For example:
> {code}
> OZONE-SITE.XML_hdds.scm.kerberos.principal: "scm/_HOST@EXAMPLE.COM"
> {code}
> It works well with scm but for om it uses the hostname instead of the FQDN. (SCM uses
the HddsServerUtil.getScmBlockClientBindAddress which uses the  _bind_ address but the om
uses the om rpc address).
> I would suggest to use the same behaviour for both SCM and OM.
