multiple queue consumers on one partition

[Wu, Jiang2]

Hi,

In our experiments, we find that if multiple consumers in the same group listen 
to the same partition, then one consumer will receive all messages on this 
partition, and others get none. Is this inherent to Kafka design, or it can be 
changed by some configuration? Basically we expect ems queue behavior, i.e., 
each of the n consumers receive about 1/n of the total messages.

Thanks,
Jiang
