title: Java consumer group missing?
body: <p>I recently set up a test Kafka cluster. I am running a consumer group listening on items and things seem to work. The name of consumer group is <code>default</code>. What surprises me is that listing consumer groups gives me an empty list:</p>
  
  <pre><code>$ ./bin/kafka-consumer-groups.sh --zookeeper localhost:2181 --list
  $
  </code></pre>
  
  <p>Also, explicitly querying the offsets doesn't yield anything:</p>
  
  <pre><code>$ ./bin/kafka-consumer-groups.sh --zookeeper localhost:2181 --describe --group default
  No topic available for consumer group provided
  GROUP, TOPIC, PARTITION, CURRENT OFFSET, LOG END OFFSET, LAG, OWNER
  </code></pre>
  
  <p><strong>Do I need to manually create a consumer group using <code>kafka-consumer-groups.sh —new-consumer</code> to be able to track its offsets?</strong></p>
