Hi, I am trying to send messages using the Kafka console producer to a Kafka broker that is running on the same machine. When I run
$ echo "Hello world" | ./kafka-console-producer.sh --broker-list localhost:9092 --topic test I receive the following error message: [2016-06-29 15:00:44,069] ERROR Error when sending message to topic test with key: null, value: 11 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback) org.apache.kafka.common.errors.TimeoutException: Batch containing 1 record(s) expired due to timeout while requesting metadata from brokers for test-0 When I check if the Kafka broker is listening on port 9092, it is there and running. How do I debug why cannot the command line producer connect to the broker? Thank you! Ludek
