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

It could be related to advertised.host.name setting in your server.properties.

What could happen is that your producer is trying to find out who is the leader for a given partition, figures out its advertised.host.name and advertised.port and tries to connect. If these settings are not configured correctly it then may think that the leader is unavailable.
