>     return getUGI(context, request, conf, AuthenticationMethod.KERBEROS_SSL, 
> true);
>   }
> {code}
> But when setup SaslConnection with server, KERBEROS_SSL will failed to create 
> SaslClient instance. See {{SaslRpcClient.java}}
> {code}
> private SaslClient createSaslClient(SaslAuth authType)
>       throws SaslException, IOException {
>       ....
>       case KERBEROS: {
>         if (ugi.getRealAuthenticationMethod().getAuthMethod() !=

>           return null; // client isn't using kerberos
>         }
