Xiao Chen resolved HADOOP-13474.
--------------------------------
    Resolution: Won't Fix

With more understanding around this area, I think this jira is not necessary.
This is because AuthenticationFilter is usually passing the authentication further down to the authentication handler, and that's where we should log more.
Will cover that in HADOOP-13174, so closing this one.

> Currently when there's an expired token, we see this from the log:
> {noformat}
> 2016-08-06 07:13:20,807 WARN org.apache.hadoop.security.authentication.server.AuthenticationFilter: AuthenticationToken ignored: AuthenticationToken expired
> 2016-08-06 09:55:48,665 WARN org.apache.hadoop.security.authentication.server.AuthenticationFilter: AuthenticationToken ignored: AuthenticationToken expired
> 2016-08-06 10:01:41,452 WARN org.apache.hadoop.security.authentication.server.AuthenticationFilter: AuthenticationToken ignored: AuthenticationToken expired
> {noformat}
> We should log a better [message|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/security/authentication/server/AuthenticationFilter.java#L456], to include more details (e.g. token type, username, tokenid) for trouble-shooting purpose.
> I don't think the additional information exposed will lead to any security concern, since the token is expired anyways.
