>                 Key: KAFKA-3969
>                 URL: https://issues.apache.org/jira/browse/KAFKA-3969
>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions: 0.10.0.0
>            Reporter: Dieter Plaetinck
>
> http://kafka.apache.org/documentation.html , at http://kafka.apache.org/documentation.html#basic_ops_consumer_lag says 
> " Note, however, after 0.9.0, the kafka.tools.ConsumerOffsetChecker tool is deprecated and you should use the kafka.admin.ConsumerGroupCommand (or the bin/kafka-consumer-groups.sh script) to manage consumer groups, including consumers created with the new consumer API."
> I'm sure that i have a consumer running, because i wrote an app that is processing data, and i can see the data as well as the metrics that confirm it's receiving data. I'm using kafka 0.10
> Yet when I run the command as instructed, it doesn't list any consumer groups
> $ /opt/kafka_2.11-0.10.0.0/bin/kafka-run-class.sh kafka.admin.ConsumerGroupCommand --zookeeper localhost:2181 --list
> $
> So either something is wrong with the tool, or with the docs.
