David Jacot commented on KAFKA-17493:
-------------------------------------
[~ChrisEgerton] [~sagarrao] I looked into many of those failed tests with more
logs and they were all due to pending members. It is basically similar to
[https://github.com/apache/kafka/pull/16567.] There is no correctness issue,
fortunately! However, I don't know why those would be flakier with the new
coordinator. There does not seem to be a specific reason for it. I will
continue to monitor it.

> We recently updated trunk to use the new KIP-848 consumer/group coordinator
> by default, which appears to have led to an uptick in flakiness for the
> OffsetsApiIntegrationTest suite for Connect (specifically, the test cases
> that use sink connectors, which makes sense since they're the type of
> connector that uses a consumer group under the hood).
> Gradle Enterprise shows that in the week before that update was made, the
> test suite had a flakiness rate of about 4%
> (https://ge.apache.org/scans/tests?search.rootProjectNames=kafka&search.startTimeMax=1724558400000&search.startTimeMin=1723953600000&search.tags=trunk&search.timeZoneId=America%2FNew_York&tests.container=org.apache.kafka.connect.integration.*&tests.sortField=FLAKY),
> and in the week and a half since, the flakiness rate has jumped to 17%
> (https://ge.apache.org/scans/tests?search.rootProjectNames=kafka&search.startTimeMax=1725681599999&search.startTimeMin=1724731200000&search.tags=trunk&search.timeZoneId=America%2FNew_York&tests.container=org.apache.kafka.connect.integration.*&tests.sortField=FLAKY).
