title: Airflow: How to SSH and run BashOperator from a different server
body: <p>Is there a way to ssh to different server and run BashOperator using Airbnb's Airflow?
  I am trying to run a hive sql command with Airflow but I need to SSH to a different box in order to run the hive shell.
  My tasks should look like this:</p>
  
  <ol>
  <li>SSH to server1</li>
  <li>start Hive shell</li>
  <li>run Hive command</li>
  </ol>
  
  <p>Thanks!</p>
