title: ReplicationFactor vs replicas in kafka
body: <p>Can we have the ReplicationFactor to 1 and no. of replicas to 3 ?</p>
  
  <pre><code>[user@master01 kafka]$ ./bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic test
  Topic:test      PartitionCount:1        ReplicationFactor:1     Configs:
      Topic: test     Partition: 0    Leader: 3       Replicas: 3     Isr: 3
  </code></pre>
  
  <p>As I understand, if ReplicationFactor is n, Replicas can be &lt;=n.
  Can someone help me understand the following scenario ? as the ReplicationFactor is set 1, where as Kafka show no. of Replicas as 3.</p>
