title: Apache Zeppelin 0.7.3 - http error 503 in browser
body: <p>Following the minimalist installation instructions from <a href="https://zeppelin.apache.org/docs/0.7.3/install/install.html" rel="noreferrer">here</a>, then on macOS High Sierra 10.13.1 executing:</p>
  
  <pre><code>bin/zeppelin-daemon.sh start
  </code></pre>
  
  <p>The daemon starts OK, but pointing any browser to <code>http://localhost:8080</code> yields</p>
  
  <pre><code>HTTP ERROR: 503
      Problem accessing /. Reason:
  
      Service Unavailable
  Powered by Jetty://
  </code></pre>
  
  <p>The same thing happens if I run as root, or if I run the browser as root, or if I install via homebrew (<code>brew install apache-zeppelin</code>).</p>
  
  <p>Permissions problem?</p>
  
  <p>What is a solution?</p>
  
  <p>Thanks!</p>
