Leader not available kafka in console producer
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 Error while fetching metadata with correlation id 39 :
{4-3-16-topic1=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)
Kafka version: 2.11-0.9.0.0
Best Answer
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.
