-----------------------------------------------------------------

[~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}

Also, I believe this applies to the case where {{--new-consumer}} is used. Correct?

> 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.
