title: Connect Spark 2.X to ElasticSearch 2.X
body: <p>I'm working with Spark and ElasticSearch and can't find how to use Spark 2.X with ElasticSearch 2.x.
  ElasticSearch Spark libs support only Spark 1.6 for ES 2.X
  and supports Spark 2 for ES 5.alpha
  What do you use to connect Spark to ElasticSearch?</p>
