Crate an elasticsearch instance. You can use the free t2.micro. I also tested with m3.medium
Change the Elasticsearch environment variable to point at the AWS Elasticsearch domain
Run all unit test or just ElasticSearchIT

Windows 10, Java 8, Amazon Elasticsearch, t2.micro, also tested with m3.medium
