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.*
> Add more debug logs for delegation tokens and authentication
