> When setup HttpFS server or KMS server in security mode, we have to config
> kerberos principal for these service, it doesn't support to convert Kerberos
> principal name pattern to valid Kerberos principal names whereas
> NameNode/DataNode and many other service can do that, so it makes confused
> for users. so I propose to replace hostname pattern with hostname, which
> should be fully-qualified domain name.
