bq. But KERBEROS_SSL is also kerberos, right?
Based on jira HDFS-3745 (unresolved), KERBEROS_SSL was meant to be SPNEGO.
Probably some leftover relic.

[~cltlfcjin] thanks for reporting the issue.
However, I don't have the problem you described. The fsck command line tool as
a client does not have problem authenticating with NN on my cluster.
Furthermore, the log you posted suggests the problem is the authentication
between the NameNode FsckServlet (which starts a dfsclient to connect to NN)
and NameNode.
If there's a bug, it is strictly a HDFS RPC authentication bug, nothing to do
with JspHelper. Because it's a HDFS RPC, it should have not used KERBEROS_SSL
at all.
Can you check if you have the correct client authentication configuration in
the NameNode configuration?

Attach some logs. I think it can be fix by two options:
# Change the enum {{AuthenticationMethod}} value KERBEROS_SSL(null) to
KERBEROS_SSL(AuthMethod.KERBEROS)
# relax the condition in createSaslClient() like
{code}
if (ugi.getRealAuthenticationMethod().getAuthMethod() !=
AuthMethod.KERBEROS && ugi.getRealAuthenticationMethod() !=
AuthenticationMethod.KERBEROS_SSL ) {
return null; // client isn't using kerberos
}
{code}
If any option is ok, I can attach the patch file.
