title: Logstash appears to be forcing multicast discovery even with embedded set to true
body: <p>I am getting the following warning and logstash is not forwarding to the embedded (built-in in logstash) ElasticSearch.</p>
  
  <p><code>WARN: org.elasticsearch.discovery: logstash [some thread id] waited for 30s and no initial state was set by the discovery</code></p>
  
  <p>I have the following in my logstash configuration.</p>
  
  <pre><code>output {
    elasticsearch {
      embedded =&gt; true
    }
  </code></pre>
  
  <p>My elasticsearch.yml has the following.</p>
  
  <pre><code># logstash embedded ES config
  script.disable_dynamic: true
  node.local: true # disable network
  </code></pre>
  
  <p>The question is how to disable discovery or make it discover the embedded ElasticSearch.</p>
