Subject [jira] [Commented] (HADOOP-13174) Add more debug logs for delegation tokens and authentication
Date Mon, 12 Jun 2017 19:25:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16046969#comment-16046969
] 

Xiao Chen commented on HADOOP-13174:
------------------------------------

Clarified with [~yzhangal] offline about his question:
bq.  provide a set of debug configuration setting here so we can refer to when needed?
>From my experience, it's usually easier if we change general log levels as the comment
above. If that's not acceptable for the environment, what we need are (from my experience):
For server:
- org.apache.hadoop.security.authentication.server.AuthenticationFilter
- org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler
- org.apache.hadoop.security.token.delegation.web.DelegationTokenAuthenticationFilter
- org.apache.hadoop.security.token.delegation.web.DelegationTokenAuthenticationHandler
- org.apache.hadoop.crypto.key.kms.server.*

For client:
- org.apache.hadoop.security.token.delegation.web.DelegationTokenAuthenticator
- org.apache.hadoop.security.token.delegation.web.DelegationTokenAuthenticatedURL
- org.apache.hadoop.security.authentication.client.KerberosAuthenticator
- org.apache.hadoop.security.authentication.client.AuthenticatedURL
- org.apache.hadoop.crypto.key.kms.*

> Recently I debugged several authentication related problems, and found that the debug
logs are not enough to identify a problem.
> This jira improves it by adding more debug/trace logs along the line.
