<p>Can somebody explain the output of the below command:</p>

<pre><code>bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --zookeeper localhost:2181 --group group1
</code></pre>

<p>Output:</p>

<pre><code>Group           Topic                          Pid Offset          logSize         Lag             Owner
group1          nil_RF2_P2                     0   2               2               0               group1_nilotpal-1469374217666-b7619d68-0
group1          nil_RF2_P2                     1   2               3               1               group1_nilotpal-1469374217666-b7619d68-0

<pre><code>bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic nil_RF2_P2  --consumer.config config/consumer1.properties
