[jira] [Updated] (HADOOP-14708) FsckServlet can not create SaslRpcClient with auth KERBEROS_SSL

["Lantao Jin (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-14708?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lantao Jin updated HADOOP-14708:
--------------------------------
    Attachment: FSCK.log

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.
