Description

Using the command:

./kafka-consumer-groups.sh --bootstrap-server=localhost:9092 --describe --group foo-group

If the CONSUMER-ID is too long the delimiter between CONSUMER-ID and HOST disappears.

Output:

TOPIC                          PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG        CONSUMER-ID                                       HOST                           CLIENT-ID
foobar-1            14         8948049         8948663         614        default-6697bb36-bf03-46e4-8f3e-4ef987177834-StreamThread-1-consumer-7c0345f5-4806-4957-be26-eb4b3bd6a9dc/10.2.3.40                     default-6697bb36-bf03-46e4-8f3e-4ef987177834-StreamThread-1-consumer

Expected output:

TOPIC                          PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG        CONSUMER-ID                                       HOST                           CLIENT-ID
foobar-1            14         8948049         8948663         614        default-6697bb36-bf03-46e4-8f3e-4ef987177834-StreamThread-1-consumer-7c0345f5-4806-4957-be26-eb4b3bd6a9dc /10.2.3.40                     default-6697bb36-bf03-46e4-8f3e-4ef987177834-StreamThread-1-consumer

I suspect that the formatting rules are incorrect https://github.com/apache/kafka/blob/0.11.0/core/src/main/scala/kafka/admin/ConsumerGroupCommand.scala#L137.
