FrankYang0529 opened a new pull request, #17056: URL: https://github.com/apache/kafka/pull/17056
In `AsyncKafkaConsumer`, `FindCoordinatorRequest` is sent by background thread. In `MockClient#prepareResponseFrom`, it only matches the response to a future request. If there is some race condition, `FindCoordinatorResponse` may not match to a `FindCoordinatorRequest`. It's better to put `MockClient#prepareResponseFrom` before the request to avoid flaky test. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
