title: Is it possible to add partitions to an existing topic in Kafka 0.8.2
body: <p>I have a <a href="https://kafka.apache.org/" rel="noreferrer">Kafka</a> cluster running with 2 partitions. I was looking for a way to increase the partition count to 3. However, I don't want to lose existing messages on the topic. I tried stopping <a href="https://kafka.apache.org/" rel="noreferrer">Kafka</a>, modifying the <code>server.properties</code> file to increase the number of partitions to 3 and restart Kafka. However, that does not seem to change anything. Using Kafka <code>ConsumerOffsetChecker</code>, I still see it is using only 2 partitions. The <a href="https://kafka.apache.org/" rel="noreferrer">Kafka</a> version I am using is 0.8.2.2. In version 0.8.1, there used to be a script called <code>kafka-add-partitions.sh</code>, which I guess might do the trick. However, I don't see any such script in 0.8.2.</p>
  <ul>
  <li>Is there any way of accomplishing this?</li>
  </ul>
  <p>I did experiment with creating a whole new topic and for that one, it does seem to use 3 partitions as per the change in the <code>server.properties</code> file. However, for existing topics, it doesn't seem to care.</p>
