--------------------------------------
[~xujianhai] that would be great. You can find instructions on how to file a PR
on "how to contribute":
https://cwiki.apache.org/confluence/display/KAFKA/Contributing+Code+Changes
If you are using IDE, you can try first reproduce the issue locally with
repeated runs and and then follow the logs to see if it is indeed a flaky test
and how to fix it.
