Gwen Shapira commented on KAFKA-3059:
-------------------------------------
One thing:
If we go the route of "ask the users to shut down all consumers in the group"
(which I find painful, but reasonable), the tool must validate that this is the
case before setting a new offset. Otherwise the results will be very
unpredictable.
> ConsumerGroupCommand should allow resetting offsets for consumer groups
