Vahid Hashemian commented on KAFKA-3144:
----------------------------------------
[~junrao] It seems the reason for this is groups with no members are marked as
"Dead" and, as a result, are not processed in ConsumerGroupCommand. The options
to change that are (1) keep the groups alive even when their members die. (2)
leave them as "Dead" but somehow retrieve their topic partition offsets. I was
wondering which option you think is the one to go with? Thanks.

> A couple of suggestions on improving ConsumerGroupCommand.
> 1. It would be useful to list members with no assigned partitions when doing
> describe in ConsumerGroupCommand.
> 2. Currently, we show the client.id of each member when doing describe in
> ConsumerGroupCommand. Since client.id is supposed to be the logical
> application id, all members in the same group are supposed to set the same
> client.id. So, it would be clearer if we show the client id as well as the
> member id.
