 <p>I had the same problem. With me it was, that I installed from Ubuntu repositories and followed the tutorials that suggested installation of elasticsearch/elasticsearch-cloud-aws/1.4.0.</p> <p>If you have done that than</p> <p><code>cd /usr/share/elasticsearch sudo bin/plugin -remove elasticsearch/elasticsearch-cloud-aws/1.4.0</code></p> <p>and to install the working version, do</p> <pre><code>cd /usr/share/elasticsearch sudo bin/plugin -install elasticsearch/elasticsearch-cloud-aws/2.2.0 </code></pre>
