Hi Tom, It's not that Kafka 2.4.0 _requires_ Zookeeper 3.5.7. Rather, previous versions of Zookeeper suffered from security vulnerabilities and when Red Hat were preparing our product based on Kafka 2.4.0 the decision was taken to ship Zookeeper 3.5.7 to avoid those vulnerabilities. IIRC 3.5.7 wasn't available at the time Apache Kafka 2.4.0 was released, was by the time we were preparing the product and was subsequently picked up for Apache Kafka 2.4.1, to avoid those same vulnerabilities.
Kind regards, Tom On Tue, Oct 6, 2020 at 6:09 AM Scott, Thomas G <thomas.g.sc...@lmco.com> wrote: > I have a quick question regarding kafka 2.4.0 and it's compatibility with > Zookeeper.
