title: reload elasticsearch after changing elasticsearch.yml
body: <p>How to make <code>elasticsearch</code> apply new configuration? 
  I changed one string in file <code>~ES_HOME/config/elasticsearch.yml</code>:</p>
  
  <pre><code># Disable HTTP completely:
  #
  http.enabled: false
  </code></pre>
  
  <p>Then tried to reload <code>elasticsearch</code>:</p>
  
  <pre><code>elasticsearch reload
  </code></pre>
  
  <p>Then tried to restart <code>elasticsearch</code>:</p>
  
  <pre><code>elasticsearch restart
  </code></pre>
  
  <p>Then checked and see that http requests are still acceptable to elastic search. </p>
  
  <p>So my settings are not applied.</p>
  
  <p>My os is <code>os X</code>. ElasticSearch version is <code>1.2.0</code></p>
