Leader Not Available Kafka in Console Producer

Question

I am trying to use Kafka.
All configurations are done properly but when I try to produce message from console I keep getting the following error

WARN Err         


        

Answer 1

If you get repeated error messages like this:

Error while fetching metadata with correlation id 3991 : {your.topic=LEADER_NOT_AVAILABLE}

Or

Discovered group coordinator 172.25.1.2:9092 (id: 2147483645 rack: null) (org.apache.kafka.clients.consumer.internals.AbstractCoordinator:677)
(Re-)joining group (org.apache.kafka.clients.consumer.internals.AbstractCoordinator:509)
Group coordinator 172.25.1.2:9092 (id: 2147483645 rack: null) is unavailable or invalid, will attempt rediscovery (org.apache.kafka.clients.consumer.internals.AbstractCoordinator:729)
Discovered group coordinator 172.25.40.219:9092 (id: 2147483645 rack: null) (org.apache.kafka.clients.consumer.internals.AbstractCoordinator:677)
Group coordinator 172.25.1.2:9092 (id: 2147483645 rack: null) is unavailable or invalid, will attempt rediscovery (org.apache.kafka.clients.consumer.internals.AbstractCoordinator:729)

Then, you need to configure listener settings like this in the kafka server.properties:

 listeners=PLAINTEXT://your.server.ip:9092

This is the solution tried on Apacke Kafka 2.5.0 and confluent platform 5.4.1.
