Question

Answer 1

Make the replication factor 2 for topic test and you won't get this exception anymore. Since you have a 2 broker cluster, execute the command below to produce messages:

kafka-console-producer.sh   --broker-list localhost:9092,localhost:9093 --topic test

This will send messages to both of the brokers in the clusters.
