Hey folks! Now that the 4.0 branch has been created, I think we need some focus on stabilizing a few flaky tests. While it is a good practice to keep our mainline branch as green as possible, I think it is especially important for release branches to be green.
Here is a report of the current situation on trunk which is essentially the same as 4.0 right now. https://github.com/apache/kafka/actions/runs/12398964575#summary-34612865771 We have a number of tests which have been quarantined, but remain unfixed. These are listed in the "Most Problematic Tests" (ignore the results with a low number of Build Scans, that's a report bug). In particular some transactions tests (both tiered and non-tiered) remain flaky. These are tracked by KAFKA-18092, KAFKA-18035, and KAFKA-18036. * testBumpTransactionalEpochWithTV2Enabled(String, String, boolean)[1] * testBumpTransactionalEpochWithTV2Disabled(String, String, boolean)[2] * testBumpTransactionalEpochWithTV2Disabled(String, String, boolean)[1] * testBumpTransactionalEpochWithTV2Enabled(String, String, boolean)[2] As per usual, PlaintextConsumerTest has some flakiness (tracked by KAFKA-18031 and KAFKA-15920) If anyone has knowledge on these areas and could investigate the flakiness, it would be super helpful. I'm sure David J (the 4.0 release manager) would love to see green builds :) Cheers, David A
