Cluster of two nodes?

[Tech Bolek <te...@yahoo.com.INVALID>]

Hello, is there any value in running zookeeper and kafka in a cluster of two nodes? I.e. one instance of zookeeper and kafka on each node?

Hi,

Regarding Zookeeper, it will not give you any higher availability running 2
instances instead of 1. You will need three Zookeeper instances to be able
to loose one. Two Zookeeper instances will simply make your Zookeeper
ensemble run slower without any benefit.

Running two nodes/brokers of Kafka should be fine. Running the on the same
instances as Zookeeper nodes should also be fine.

Cheers,
Jens
