With the incompatibility of Spark 2.0 with Spark 1.3-1.6, we split the one spark artifact into two separate ones. The Spark 2.0/Scala 2.11 artifact can be found here : https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch-spark-20_2.11
For the old 1.3-1.6 support level for spark, it can be found here :
https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch-spark-13_2.11
The Scala 2.10 versions of standalone alpha 5 spark support can be found here :
https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch-spark-20_2.10
and here:
