Consumer not receiving messages, kafka console, new consumer api, Kafka 0.9

Question

I am doing the Kafka Quickstart for Kafka 0.9.0.0.

I have zookeeper listening at localhost:2181 because I ran

bin/zookeeper-server-start.sh          


        

Answer 1

In my case, this doesn't work

kafka-console-consumer --bootstrap-server localhost:9092 --from-beginning --topic my-replicated-topic

and this works

kafka-console-consumer --bootstrap-server localhost:9092 --from-beginning --topic my-replicated-topic --partition 0

because the topic __consumer_offsets was located on the unaccessible broker. Basically, I'd forgotten to replicate it. Relocating __consumer_offsets solved my issue.
