Re: [VOTE] 4.3.2 RC0
Posted by Bill Bejeck <bb...@gmail.com>.
Hi Jiunn-Yang,
Thanks for running the 4.3.2 release.
I did the following to validate 4.3.2-rc0:
- Verified checksums (md5/sha1/sha512) and GPG signatures
- Artifacts: source, binary, site-docs, RELEASE_NOTES
- Signed by Jiunn Yang Huang <jy...@apache.org>
- Key 062C22C0F467AF9A02D512B5504473FAF80CBBCB
- Built from source with JDK 17
- Ran the core, clients and streams unit tests
- Ran quickstarts from the bundled site-docs against the binary
distribution
- 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-rc0
- apache/kafka-native:4.3.2-rc0
- Checked shipped jar versions for the dependency and CVE bumps
- jackson-databind 2.21.6
- log4j 2.25.5
- jetty 12.0.37
- lz4-java 1.11.2
- jline 3.30.15 (jline-remote-telnet no longer shipped)
- Exercised these bug fixes by hand against local clusters
- Streams:
- KAFKA-14597, KAFKA-20464, KAFKA-20711, KAFKA-20782
- KAFKA-20876, KAFKA-20877, KAFKA-20940
- Broker:
- KAFKA-20354 (docs), KAFKA-20434, KAFKA-20442, KAFKA-20533
- KAFKA-20601, KAFKA-20832, KAFKA-21096
- Clients:
- KAFKA-20700, KAFKA-20769, KAFKA-20780
- Connect:
- KAFKA-20450, KAFKA-20555
I noticed a few minor non-blocking issues:
- The apache/kafka link in the vote email carries
sha256:aad4e610..., which is the linux/amd64 manifest of
apache/kafka-native. The apache/kafka:4.3.2-rc0 index is
sha256:5bd263149a366634adda4a2963aa8d80e7430b8eaa09bb685058df883f957b48
- These JIRAs have commits in 4.3.2-rc0 but no fix version, so
they are missing from RELEASE_NOTES.html:
- KAFKA-13499 (windowed restore now skips expired records)
- KAFKA-20870, KAFKA-20875, KAFKA-20916
- The quickstarts still reference 4.3.0 downloads and tags
+1 (binding)
Thanks,
Bill

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

Hi Bill,
Thanks a lot for the thorough verification.
On KAFKA-20870: that one is intentionally left without a fix version. It is still open
and labelled needs-kip, the discussion on the thread has not settled on a direction yet.
So I would rather not pull it into the 4.3.2 release notes. I will go through the other three
and add the fix version where the ticket is actually resolved.

Hello all,
Thanks for testing the 4.3.2-rc0 release. However, there are a few critical
issues that have been fixed and backported since 4.3.2-rc0 was released.
I'll prepare a new RC with these changes included.

Hi Jiunn-Yang,
Thanks for running the release. I verified 4.3.2-rc0 as follows:
Checksums (md5/sha1/sha512) and signatures of all artifacts, plus the staged kafka-clients Maven artifacts. Signed by 062C22C0F467AF9A02D512B5504473FAF80CBBCB, which is in KEYS.
Source tarball matches the 4.3.2-rc0 tag (bc6c0af7).
Shipped jar versions match the dependency bumps and LICENSE-binary. jline-remote-telnet is no longer shipped.
Ran the full test suite from source with JDK 25. All passed; only a few known flaky tests needed a retry.
Smoke tested the binary with JDK 25: KRaft broker, produce/consume, consumer group, Streams WordCount with the streams protocol, and Connect FileStreamSource.
Ran produce/consume against both Docker images.
I noticed that 4.3 has two commits after the RC tag (#23669 and #23627). Please double check whether they are intended for 4.3.2.
+1 (binding)
Thanks,
Chia-Ping

Re: [VOTE] 4.3.2 RC0
Posted by Bill Bejeck <bb...@gmail.com>.
Hi Jiunn-Yang,
Thanks for running the 4.3.2 release.
I did the following to validate 4.3.2-rc0:
- Verified checksums (md5/sha1/sha512) and GPG signatures
- Artifacts: source, binary, site-docs, RELEASE_NOTES
- Signed by Jiunn Yang Huang <jy...@apache.org>
- Key 062C22C0F467AF9A02D512B5504473FAF80CBBCB
- Built from source with JDK 17
- Ran the core, clients and streams unit tests
- Ran quickstarts from the bundled site-docs against the binary
distribution
- 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-rc0
- apache/kafka-native:4.3.2-rc0
- Checked shipped jar versions for the dependency and CVE bumps
- jackson-databind 2.21.6
- log4j 2.25.5
- jetty 12.0.37
- lz4-java 1.11.2
- jline 3.30.15 (jline-remote-telnet no longer shipped)
- Exercised these bug fixes by hand against local clusters
- Streams:
- KAFKA-14597, KAFKA-20464, KAFKA-20711, KAFKA-20782
- KAFKA-20876, KAFKA-20877, KAFKA-20940
- Broker:
- KAFKA-20354 (docs), KAFKA-20434, KAFKA-20442, KAFKA-20533
- KAFKA-20601, KAFKA-20832, KAFKA-21096
- Clients:
- KAFKA-20700, KAFKA-20769, KAFKA-20780
- Connect:
- KAFKA-20450, KAFKA-20555
I noticed a few minor non-blocking issues:
- The apache/kafka link in the vote email carries
sha256:aad4e610..., which is the linux/amd64 manifest of
apache/kafka-native. The apache/kafka:4.3.2-rc0 index is
sha256:5bd263149a366634adda4a2963aa8d80e7430b8eaa09bb685058df883f957b48
- These JIRAs have commits in 4.3.2-rc0 but no fix version, so
they are missing from RELEASE_NOTES.html:
- KAFKA-13499 (windowed restore now skips expired records)
- KAFKA-20870, KAFKA-20875, KAFKA-20916
- The quickstarts still reference 4.3.0 downloads and tags
+1 (binding)
Thanks,
Bill
