Leader brokers without a matching listener error in kafka

Question

What is the meaning of this kafka error ?

[2018-08-22 11:40:49,429] WARN [Consumer clientId=consumer-1, groupId=console-consumer-62114] 1 partitions hav

Answer 1

In my case, i was getting this error when i was testing Kafka fail-over. I brought down 1 Kafka, and expected the message to be written to the other Kafka.

The issue was that topic replication-factor was set to 1, when i needed to set it to 2. (2 Kafka instances)

Bonus:
Check out the directories where the topics are created(in my case: kafka-logs-xx) for both Kafka, and you will understand why :-)
