Hey Eno, Vahid and everyone, Thanks for reporting the test error! https://builds.apache.org/job/kafka-2.1-jdk8/ shows the list of recent unit test runs. 7 out of 10 recent runs have passed all tests. Each of the three runs shows one unique flaky test failure.
I have opened umbrella JIRA https://issues.apache.org/jira/browse/KAFKA-7645 to track these flake test. There are currently 7 flaky tests reported in either https://builds.apache.org/job/kafka-2.1-jdk8/ or the voting threads. Among these 7 flaky tests, 3 tests failed due to issue in the test logic, 3 tests are related SSL with similar failure in 2.0 branch which has been running well. So these 6 tests should not be blocking issue for 2.1.0 release. Regarding the other test failure for LogCleanerParameterizedIntegrationTest.testCleansCombinedCompactAndDeleteTopic (KAFKA-7647 <https://issues.apache.org/jira/browse/KAFKA-7647>). I did due diligence to understand the failure but could not find any bug. Since this test failure happens rarely and I could not find any issue by looking at the stacktrace, I am again inclined not to consider this as blocking issue. We can discuss more if there is different opinion in the mailing list.
