Vahid Hashemian commented on KAFKA-3144:
----------------------------------------
[~junrao] How do you think the consumer group coordinator (I assume the broker
id is sufficient) should be displayed in the output?
One option would be in a new {{COORDINATOR}} column (which repeats the same id
in each row similar to how group name gets repeated):
{code}
GROUP COORDINATOR TOPIC PARTITION CURRENT-OFFSET
LOG-END-OFFSET LAG MEMBER-ID MEMBER-HOST
CLIENT-ID
group1 0 bar 0 445 445
0 group1_kafka-1472762710305-24f2ffa3
{code}
> report members with no assigned partitions in ConsumerGroupCommand

>
> 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.
