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}

> 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.
