Subject Re: Kafka compatibility with ZK
Date Sun, 02 Aug 2020 17:03:31 GMT

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
