Mapping topic partition owner id to group member id?

[Vahid S Hashemian <va...@us.ibm.com>]

Hi,

The consumer group command directly uses ZooKeeper (through zkUtils) to 
return information about a consumer group.
Inside a /consumers/[group]/ structure member ids exist under ids/ and 
owner information for each topic partition is under 
owners/[topic]/[partition]/.

An example member id is "[group]_kafka-1462299650388-4b3e54e4", while its 
corresponding owner id (if it's in fact an owner of some partition) is 
"[group]_kafka-1462299650388-4b3e54e4-0".
I am wondering what's the best way of mapping owner id to member id and 
vice versa within a consumer group.

Thanks.

I forgot to mention that my question is in the context of the old 
consumer.
