title: What does "Broker transport failure" mean in kafka?
body: <p>I am using a python client(Confulent kafka) to consume from kafka.  Some times the consumer will hit error like below:</p>
  
  <pre><code>ERROR KafkaError{code=_TRANSPORT,val=-195,str="GroupCoordinator response error: Local: Broker transport failure"}
  </code></pre>
  
  <p>Can someone help to explain what does the error mean?  "transport failure" seems mean the consumer is having network issue with the broker, is that right? what should I do when this error happen?</p>
