Description

It would appear that the latest iteration of the ConsumerGroupCommand no longer outputs information about group membership when no offsets have been committed. It would be nice if the output generated by these tools maintained some form of consistency across versions as some users have grown to depend on them.

0.9.x output:

bin/kafka-consumer-groups --bootstrap-server localhost:9092 --new-consumer --describe --group console-consumer-34885
GROUP, TOPIC, PARTITION, CURRENT OFFSET, LOG END OFFSET, LAG, OWNER
console-consumer-34885, test, 0, unknown, 0, unknown, consumer-1_/192.168.1.64

0.10.2 output:
bin/kafka-consumer-groups --bootstrap-server localhost:9092 --new-consumer --describe --group console-consumer-34885
Note: This will only show information about consumers that use the Java consumer API (non-ZooKeeper-based consumers).
