title: Start multiple brokers in kafka
body: <p>Beginner in kafka and confluent package.I want to start multiple brokers so as to consume the topic.
  It can be done via this setting -
   <code>{'bootstrap.server' : 'ip:your_host,...',}</code></p>
  
  <p>This setting can be defined in the server config file or else in the script as well.</p>
  
  <p>But how shall I run those?. If I just add multiple end points to the bootstrap servers, it gives this error:    </p>
