title: WebHDFS vs HttpFS
body: <p>What is the difference between the <a href="http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/WebHDFS.html" rel="noreferrer">WebHDFS REST API</a> and <a href="http://hadoop.apache.org/docs/current/hadoop-hdfs-httpfs/index.html" rel="noreferrer">HttpFS</a>?</p>
  
  <p>If I understand correctly:</p>
  
  <ul>
  <li>HttpFS is an independent service that exposes a REST API on top of HDFS</li>
  <li>WebHDFS is a REST API built-into HDFS. It doen't require any further installation </li>
  </ul>
  
  <p>Am I correct?</p>
  
  <p>When would be advisable to use one instead of the other? </p>
