title: Titan loading problems with elastic search
body: <p>I'm using the following code to load Titan:</p>
  
  <pre><code>TitanFactory.Builder config = TitanFactory.build();
      config.set("storage.backend", "berkeleyje");
      config.set("storage.directory", DIRECTORY);
      //config.set("storage.conf-file", "file:////" + DIRECTORY + "/cassandra/cassandra.yaml");
      config.set("index." + INDEX_NAME + ".backend", "elasticsearch");
      config.set("index." + INDEX_NAME + ".DIRECTORY", DIRECTORY + File.separator + "es");
      config.set("index." + INDEX_NAME + ".elasticsearch.local-mode", true);
      config.set("index." + INDEX_NAME + ".elasticsearch.client-only", false);
  
      graph = config.open();
  </code></pre>
  
  <p>loading dependencies with gradle:</p>
  
  <pre><code>compile group: 'com.thinkaurelius.titan', name: 'titan-all', version: '1.0.0'
  </code></pre>
  
  <p>My project directory is:</p>
  
  <p>/home/ray/IdeaProjects/BAG - Byzantine fault-tolerant Architecture for Graph database/</p>
  
  <p>my titan is in this project directory in the folder "TITAN"
  That's what I set in the Directory variable.</p>
  
  <p>Still on start it always crashes:</p>
