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

I just ran into this issue and the solution was to delete /brokers in zookeeper and restart the kafka nodes.

bin/zookeeper-shell :2181

and then

rmr /brokers

Not sure why this solves it.

When I enabled debug logging, I saw this error message over and over again in the consumer:
