Actually, I'm very interested in your experience as well.... I'm about to start the same (similar) upgrade - from Kafka 0.11/ZK3.4.13 to Kafka 2.4/ZK 3.5.6
I have Kafka and ZK as separate clusters. My plan is : 1. rolling upgrade the Kafka cluster to 2.4 - using the inter.broker.protocol.version set to 0.11 at first 2. rolling upgrade ZK cluster to 3.5.6 3. set inter.broker.protocol.version=2.4.0 and rolling restart the Kafka cluster again Anybody sees a problem with this approach? thanks, Marina Sent with ProtonMail Secure Email. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Thursday, July 23, 2020 4:01 PM, Andrey Klochkov <[email protected]> wrote: > Hello, > We're upgrading our Kafka from 1.1.0 to 2.4.1 and I'm wondering if ZK needs > to be upgraded too (we're currently on 3.4.6).
