>                 Key: HADOOP-14708
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14708
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: security
>    Affects Versions: 2.7.3, 2.8.1, 3.0.0-alpha3

> FSCK started by xx (auth:KERBEROS_SSL) failed with exception msg "fsck encountered internal
errors!"
> FSCK use FSCKServlet to submit RPC to NameNode, it use {{KERBEROS_SSL}} as its {{AuthenticationMethod}}
in {{JspHelper.java}}
> {code}
>   /** Same as getUGI(context, request, conf, KERBEROS_SSL, true). */
>   public static UserGroupInformation getUGI(ServletContext context,
>       HttpServletRequest request, Configuration conf) throws IOException {
>     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() !=
>             AuthMethod.KERBEROS) {
>           return null; // client isn't using kerberos
>         }
> {code}
