amazon ec2 - Kafka : How to connect kafka-console-consumer to fetch remote broker topic content?

Question

I have setup a kafka zookeeper and 3 brokers on one machine on ec2 with ports 9092..9094 and am trying to consume the topic content from another machine. The ports 2181 (zk), 9092, 9093 and 9094 (servers) are open to the consumer machine. I can even do a bin/kafka-topics.sh --describe --zookeeper 172.X.X.X:2181 --topic remotetopic which gives me

Topic:remotetopic PartitionCount:1 ReplicationFactor:3 Configs: Topic: remotetopic Partition: 0 Leader: 2 Replicas: 2,0,1 Isr: 2,0,1 Blockquote

However when i do bin/kafka-console-consumer.sh --zookeeper 172.X.X.X:2181 --from-beginning --topic remotetopic I get

WARN Fetching topic metadata with correlation id 0 for topics [Set(remotetopic)] from broker [id:0,host:localhost,port:9092] failed (kafka.client.ClientUtils$) java.nio.channels.ClosedChannelException

Why is the consumer trying to read from localhost? Is there any option or commandline or default file where this is read from; and I can change it?

Any help would be appreciated!

Answer 1

I had same problem , I am using kafka 0.11 and I started producer and broker in my Ubuntu VM and consumer in Windows 10.

I had changed (and uncommented)

advertised.listeners=PLAINTEXT://your.host.name:9092

to

advertised.listeners=PLAINTEXT://<myActual IP address>:9092

example:

advertised.listeners=PLAINTEXT://192.168.150.150:9092

from file config/server.properties at server/broker side (i.e. in my case it was Ubuntu VM)
