Hi,

I am using Elasticsearch 2.2.0, Kibana 4.4.2, Shield 2.2, Php 5.4.45. I want to index mysql data but it isnt't work. My error :

Fatal error: Class 'GuzzleHttp\Ring\Client\CurlMultiHandler' not found in /home/admin/web/server.com/public\_html/vendor/elasticsearch/elasticsearch/src/Elasticsearch/ClientBuilder.php on line 141

What is the problem?
