Hi, I see that the version of elastic-search used in external/storm-elasticsearch/pom.xml is quite old (1.6.0) while the latest elastic-search is 2.2.0
2.x version is not compatible with 1.x version of elastic-search and so I request you to upgrade. Also, current storm-elasticsearch uses TransportClient of elastic-search but does not expose many of the useful options in the TransportClient (like routing). Request you to expose them to the users too. Thanks Tid
