Hi Mickael, I did the following: - Built from source with Java 23 zulu - Validated all checksums and signatures - Ran unit tests&integration tests - Ran quick-start for streams with kafka-native 4.1.0-rc3 image - Ran instructions with dynamic voter set - Skimmed the rc3 doc
I noticed that the documentation for the dynamic voter set needs to be updated. I’ve already opened a PR for this: https://github.com/apache/kafka-site/pull/713 <https://github.com/apache/kafka-site/pull/713?utm_source=chatgpt.com>. It would be great if we could get this merged before the 4.1.0 release. +1 (non-binding) Thanks, Kuan-Po Tseng On Sat, Aug 30, 2025 at 4:03 AM Mickael Maison <mickael.mai...@gmail.com> wrote: > Hi Justine, > > Yes this is a known issue, tracked in > https://issues.apache.org/jira/browse/KAFKA-18973 > > Thanks, > Mickael > > On Fri, Aug 29, 2025 at 8:44 PM Justine Olshan > <jols...@confluent.io.invalid> wrote: > > > > Hi Mickael, > > > > I've done the following: > > -
