title: Verify if Kafka queue is empty
body: <p>We have pushed messages onto kafka queues 2 days back and the retention is set to 2 days so its going to expire today . Is there any way of knowing exactly when kafka queues are empty/not having any data in them?</p>
  
  <p>I am a beginner in Hadoop system so I don't know if there is any command to find this/easy way to verify the empty queues</p>
