Subject [jira] [Created] (HADOOP-13474) Add more details in the log when a token is expired
Date Mon, 08 Aug 2016 21:06:21 GMT
Xiao Chen created HADOOP-13474:
----------------------------------

             Summary: Add more details in the log when a token is expired
                 Key: HADOOP-13474
                 URL: https://issues.apache.org/jira/browse/HADOOP-13474
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 2.6.0
            Reporter: Xiao Chen
            Assignee: Xiao Chen


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.
