Apache Kafka example error: Failed to send message after 3 tries

Question

I am running this kafka producer example mentioned in its site

The code:

public class TestProducer {

    public static void main(String[] args) {
               


        

Answer 1

ForHDP kafka use broker port: 6667

For Standalone kafka use broker port: 9092

The error was because of the port no which we were using (HDP uses 6667 but we were using 9092)

bin/kafka-console-producer.sh --broker-list broker-ip:9092 --topic test //not working

bin/kafka-console-producer.sh --broker-list broker-ip:6667 --topic test //working
