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

I'm using kafka_2.12-0.10.2.1:

vi config/server.properties

add below line:

listeners=PLAINTEXT://localhost:9092

• No need to change the advertised.listeners as it picks up the value from std listener property.

Hostname and port the broker will advertise to producers and consumers. If not set,

• it uses the value for "listeners" if configured

Otherwise, it will use the value returned from java.net.InetAddress.getCanonicalHostName().

stop the Kafka broker:

bin/kafka-server-stop.sh

restart broker:

bin/kafka-server-start.sh -daemon config/server.properties

and now you should not see any issues.
