Find broker id used in the Kafka cluster
<p>I want to know the list of taken broker ids in a kafka cluster. For example, in a cluster with 10 nodes if I create a topic with 10 partitions(or more) I can see from the output of a describe topic command, the brokers to which it has been assigned. </p>

<pre><code>./bin/kafka-topics --describe --zookeeper &lt;zkconnect&gt;:2181 --topic rbtest3
</code></pre>

<p>Can I collect this information without creating a topic?</p>
