Why __consumer_offsets topic in kafka is not spreading to all the brokers?

Question

I have a 3 zk nodes cluster. And 7 kafka broker nodes.

So when I create any topic then I can set replica factor and no of partitions us

Answer 1

You need to set the "offsets.topic.replication.factor" to the desired number of replicas in the broker config.

offsets.topic.replication.factor - "The replication factor for the offsets topic (set higher to ensure availability). Internal topic creation will fail until the cluster size meets this replication factor requirement."
