Who is assigned to which partitions

[Per Steffensen]

As a Kafka consumer I know which topic-partitions I am assigned to 
within my consumer-group. What is the easiest way, as a client, to get a 
complete overview of the assignments within the consumer-group - 
specifically who (client-id, host/IP, port etc (whatever is available)) 
is assigned to the partitions I am not assigned to.

Thanks!
