Re: [VOTE] 4.3.2 RC3
Posted by Eric Chang <e8...@gmail.com>.
Hi Jiunn-Yang,
Thanks for running the release. I verified 4.3.2-rc3 as follows:
- Verified the SHA512 checksums and GPG signatures of the source and
binary tarballs. They are signed by Jiunn Yang Huang, whose key is
in KEYS.
- Built from source with JDK 17 (./gradlew clean build -x test).
- Ran the clients and core unit tests. All core tests passed. One
clients test failed once (SaslAuthenticatorTest
.testValidSaslScramMechanisms). It passed in 5 reruns, and
SaslAuthenticatorTest is already flaky on Develocity, so I think it
is a flaky test.
- Started a KRaft broker from the binary tarball with JDK 17. Produced
and consumed with none, gzip, snappy, lz4 and zstd compression.
- Started apache/kafka:4.3.2-rc3 and apache/kafka-native:4.3.2-rc3
with the default config (using podman). Produce and consume work on
both.
- Ran the full system tests on the rc3 commit (0a6c96d3):
https://jenkins.opensource4you.tw/job/kafka-e2e/975/
1116 tests, 1103 passed, 11 failed. I checked the logs of all 11
failures. They are known flaky tests or timing issues, and none of
them is related to this release.
+1 (non-binding)
Best,
Eric

Re: [VOTE] 4.3.2 RC3
Posted by David Jacot <da...@gmail.com>.
Hi Jiunn-Yang,
Thanks for running the release.
I did the following to validate RC3:
- Verified the signatures and checksums of the source, binary, site-docs
and release notes artifacts, and of all the staged Maven artifacts
- Checked that the source tarball matches the 4.3.2-rc3 tag
- Built from source and ran the unit tests with JDK 17 and JDK 25
- Ran the quickstart with the binary on JDK 17 and JDK 25, with classic
and consumer groups
- Did a rolling upgrade of a 3-node combined cluster from 4.3.1 to
4.3.2 while producing and consuming (classic and consumer groups)
- Ran the apache/kafka and apache/kafka-native images
- Built a small producer/consumer/admin app against the staged Maven
artifacts and ran it with JDK 17 and JDK 25
- Spot checked the release notes, Javadoc and documentation
+1 (binding)
Best,
David

Hi Jiunn-Yang,
Thanks for running the 4.3.2 release.
I did the following to validate RC3:
- Verified checksums (md5/sha1/sha512) and GPG signatures
- Artifacts: source, binary, site-docs, RELEASE_NOTES
- Signed by Jiunn Yang Huang <jy...@apache.org>

- Built from source with JDK 17
- Ran the core, clients and streams unit tests
- Ran quickstarts from the bundled site-docs against the binary dist
- Broker quickstart
- Kafka Streams WordCount quickstart
- Used both the classic and streams (KIP-1071) group protocols
- Ran the same quickstarts against the Docker images
- apache/kafka:4.3.2-rc3
- apache/kafka-native:4.3.2-rc3

Hi,
I did the following testing:
- checked signatures and checksums
- built from source
- ran quickstart with Java 20 and both docker images
Just one nit: the javadoc were generated with <html lang="zh">, so
most browsers bring up the translation dialog when you open them

+1 (non-binding). I used the staged binaries and Maven artifacts to run my
smoke tests & the Strimzi tests. All seems to work fine. Thanks for running

Verified the following:
- signatures and checksums of source/binary tarballs and staged maven artifacts
- source tarball builds; ran unit and integration tests locally (a few
streams/MM2 integration tests timed out on the first pass due to local
resource limits, all passed on re-run)
- started a KRaft broker from the binary tarball, produce/consume works
- apache/kafka:4.3.2-rc3 and apache/kafka-native:4.3.2-rc3 start with the
default config and accept client connections
- javadoc, release notes, and documentation links
Two small notes:
- the hyperlinks behind "Release notes" and "Release artifacts" point to
4.3.2-rc/ instead of 4.3.2-rc3/ (the visible text is correct)
- system test results are still marked as "will provide it soon"
Thanks for running the release, Jiunn-Yang.
