---------------------------------------

             Summary: kafka.admin.ConsumerGroupCommand doesn't show consumer groups
                 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.
