----------------------------------
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.
