Kafka

Hmm, I think we could have been dropping each other but I also have triggered 4.4 RC1 couple of times so it could be the re-triggering path caused issue to 4.4 RC. I will trigger new RC today and hopefully this will fix it for 4.4.0 Sent from my iPhone > On 23 Sep 2026, at 22:21, Jakub Scholz <jakub@scholz.cz> wrote: > > Hi Omnia, > > Thanks for the RC. > > There seems to be the same problems as with the 4.2.2 RC and the staged > Maven artifacts seem to be missing in the staging repo.

Hi Vivek, Because of the process for releasing versions in the ASF, we can't really give you an exact date until the very same day the release happens (or in some cases a couple of days before). Each Release Candidate is proposed and must be validated by the community and maintainers. Currently, we are testing RC1 and it seems there are some problems. So probably another release candidate needs to be created.

Hi Omnia, Thanks for the RC. There seems to be the same problems as with the 4.2.2 RC and the staged Maven artifacts seem to be missing in the staging repo. (I wonder if for some reason both RCs were dropped by the Maven repo or if there is some issue with doing two releases in parallel and you are overwriting each other 🤔) Thanks Jakub On Tue, Sep 22, 2026 at 4:10 PM Omnia Ibrahim <o.g.h.ibrahim@gmail.com> wrote: > Hello Kafka users, developers and client-developers, > > This is the 2nd candidate for release of Apache Kafka 4.4.0. > > Apache Kafka 4.4.0 is a minor release that includes 26 KIPs spanning > improvements to all components. > > Release notes for the 4.4.0 release: > https://dist.apache.org/repos/dist/dev/kafka/4.4.0-rc1/RELEASE_NOTES.html > > Please download, test and vote by Friday, September 25, 2026, 12:30pm BST > (4:30am PT) > > Kafka's KEYS file containing PGP keys we use to sign th...

Hi Omnia I tested the 4.4 branch and encountered a test failure, but it is unrelated to 4.4 branch. see https://issues.apache.org/jira/browse/KAFKA-21146 for details Best, Chia-Ping Omnia Ibrahim <o.g.h.ibrahim@gmail.com> 於 2026年9月23日週三 下午6:18寫道： > Adding both users and Kafka-clients > > > On 23 Sep 2026, at 11:11, Omnia Ibrahim <o.g.h.ibrahim@gmail.com> wrote: > > > > Here is the report for system testing > > > > > https://confluent-open-source-kafka-branch-builder-system-test-results.s3-us-west-2.amazonaws.com/trunk/2026-09-22--001.1442301f-18b4-4a90-a790-4f8550f93d20--1790111851--apache--4.4--812f9108eb/report.html > > The two failed test cases are same as the one mentioned in 4.3.1 RC2 so > not new issue > > > >> On 22 Sep 2026, at 15:09, Omnia Ibrahim <o.g.h.ibrahim@gmail.com> > wrote: > >> > >> Hello Kafka users, developers and client-developers, ...

Hi Benson, Yes, your steps look correct to me. The migration to combined nodes should work. Just be noted, if you want to add some lagged nodes into the voters, it might impact the quorum because it needs the majority of nodes to be caught up.
