Guozhang Wang commented on KAFKA-1476:
--------------------------------------
You are already ahead of us, since the coordinator is still under development
:) We just wanted to think in advance of what kind of consumer queries we would
like tooling now and in the future, and they can be easily implemented with the
proposed design.
> Get a list of consumer groups

> Key: KAFKA-1476

> Issue Type: Wish

> It would be useful to have a way to get a list of consumer groups currently
> active via some tool/script that ships with kafka. This would be helpful so
> that the system tools can be explored more easily.
> For example, when running the ConsumerOffsetChecker, it requires a group
> option
> bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --topic test --group
> ?
> But, when just getting started with kafka, using the console producer and
> consumer, it is not clear what value to use for the group option. If a list
> of consumer groups could be listed, then it would be clear what value to use.
