Unable to reset kafka offset in a consumer group

Hi All,

I'm trying to reset a kafka offset for a topic in a consumer group, i
have stopped all the consumers using the consumer group but i'm still
receiving the message that the current state is stable.

Is there a way to put the consumer group to an inactive state after
stopping all the consumers or is there a way to force the offset forward
by an increment of 1 just for this topic?

Many Thanks,

Chris
