      Description

      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

        /** 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);
        }
      

      But when setup SaslConnection with server, KERBEROS_SSL will failed to create SaslClient instance. See SaslRpcClient.java

      private SaslClient createSaslClient(SaslAuth authType)
            throws SaslException, IOException {
            ....
            case KERBEROS: {
              if (ugi.getRealAuthenticationMethod().getAuthMethod() !=
                  AuthMethod.KERBEROS) {
                return null; // client isn't using kerberos
              }
