title: Ambari Server java process died with exitcode -1
body: <p>I can't start ambari-server after finishing installation and setup of ambari-server on Ubuntu16.04. This is the error message I get:</p>
  <blockquote>
  <p>ERROR: Exiting with exit code -1.</p>
  <p>REASON: Ambari Server java process died with exitcode -1. Check /var/log/ambari-server/ambari-server.out for more information.</p>
  </blockquote>
  <p>What's more, there is only ambari-server.log instead of ambari-server.out</p>
  <p>Could someone help me？ Thanks in advance.</p>
