Thanks for running the release Lianet!
- Downloaded all artifacts and verified signatures
- Built from source and ran all unit & integration tests locally
(OpenJDK 17)
Got a unit test failure, which fails all the time. So I am not sure how
we could get a passing CI build? Is the test not included in the build
(quarantined)?
org.apache.kafka.connect.data.ValuesTest.shouldConvertDateValues() failed, log

I found
https://github.com/apache/kafka/commit/3fcc0c287795c6a591216617e0d5a02bd6fdbfc3
which is only in `trunk` and fixes the test for me (applied on top of
4.1.1-rc2 code).
So this does not block the release, but we should cherry-pick this fix
to `4.1` branch?
Flaky integration tests:
- kafka.api.PlaintextConsumerTest
- kafka.server.ReconfigurableQuorumIntegrationTest
- kafka.coordinator.transaction.ProducerIntegrationTest
-org.apache.kafka.connect.mirror.integration.MirrorConnectorsIntegrationBaseTest
- org.apache.kafka.clients.consumer.ShareConsumerRackAwareTest
- org.apache.kafka.clients.producer.ProducerFailureHandlingTest
-
org.apache.kafka.streams.integration.KafkaStreamsTelemetryIntegrationTest
- org.apache.kafka.tools.consumer.ConsoleConsumerTest
- org.apache.kafka.tools.ConfigCommandIntegrationTest
- org.apache.kafka.tools.streams.DescribeStreamsGroupTest
Permanent test failures -- but it seems to be an issue with my local
env, as talking to some others they cannot reproduce it, and CI build
also passed.
- kafka.network.SocketServerTest> java.lang.NoClassDefFoundError:

- Run Quickstart
- Tested KS quickstart with "streams" groups enabled

+1 (non-binding). I used the staged binaries and run my own tests with it
as well as the Strimzi system tests. All seems to work fine.
