title: Kafka Only One Consumer in Consumer Group Getting Messages
body: <p>In my setup, I have a consumer group with three processes (3 instances of a service) that can consume from Kafka.  What I've found to be happing is that the first node is receiving all of the traffic. If one node is manually killed, the next node picks  up all Kafka traffic, but the last remaining node sits idle.</p>
  
  <p>The behavior desired is that all messages get distributed evenly across all instances within the consumer group, which is what I thought should happen. As I understand, the way Kafka works is that it is supposed to distribute the messages evenly amongst all members of a consumer group. Is my understanding correct? I've been trying to determine why it may be that only one member of the consumer group is getting all traffic with no luck. Any thoughts/suggestions?</p>
