title: kafka cluster expansion generic step
body: <p>We are planning to expand cluster from 2 node to 8 node. The partition reassignment tool has the option to move topic or partition.</p>
  <p>For re-distribution of partitions I am planning to follow the below steps.</p>
  <p>Irrespective of number of  node additions,If I give all the topics in the topic-to-move.json and all the brokers in the below command then it will give equal distribution of partition among nodes correct ?</p>
  <pre><code> bin/kafka-reassign-partitions.sh --zookeeper localhost:2181 --topics-to-move-json-file topics-to-move.json --broker-list &quot;0,1,2,3,4,5,6,7&quot; --generate
  </code></pre>
  <p>After this I am planning to apply the json</p>
  <pre><code>--execute --reassignment-json-file generated-json file
  </code></pre>
  <p>Will this cause any problem ?</p>
  <p>This step seems to be more general but why it is not documented this way?</p>
