Lantao Jin commented on HADOOP-14708:
-------------------------------------
Sorry I don't know why the ugi client in NN (in FSCK servlet) use KERBEROS_SSL.
I guess it inherited from the JspHelper. But I wonder the logical any
KERBEROS_SSL from rpc can not pass through the NEGOTIATE.
Return {{null}} illustrate that client isn't using kerberos. But KERBEROS_SSL
is also kerberos, right? Please correct me if I misunderstand.
> FsckServlet can not create SaslRpcClient with auth KERBEROS_SSL

> 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
