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.

Thanks,
Dong
