title: Elasticsearch minimum master nodes
body: <p>I have a 3 node cluster with <code>minimum_master_nodes</code> set to <code>2</code>. If I shut down all nodes <strong>except the master</strong>, leaving one node online, the cluster is no longer operational.</p>
  
  <p>Is this by design? It seems like the node that was the master shouldd remain operational, instead I get errors like this:</p>
  
  <pre><code>{"error":"MasterNotDiscoveredException[waited for [30s]]","status":503}
  </code></pre>
  
  <p>All the other settings are stock and I am using the aws cloud plugin.</p>
