Answer 1

Don't know if this answer is still relevant but recently resolved this same problem in a VBox VM broker not reachable from host Windows OS. Since you have mentioned bootsrap_servers in KafkaConsumer, I assume you are using at least kafka 0.10.0.0

Please look for the advertised.listeners property in server.properties file and set it to PLAINTEXT://localhost:9092 or PLAINTEXT://:9092

But before you set that make sure your broker is reachable from the environment where your consumer is running (by doing ping localhost).

Also, you need to restart the kafka-server and consumer/producer (whatever is running) and try sending/receiving.

For example, if you are running VM, you may like to use Host-only adapter to make the broker reachable from host machine

NOTE: This configuration works for Kafka Server >= 0.10.X.X but not for 0.8.2.X. Haven't checked for 0.9.0.X
