My POM has

- org.apache.spark.spark-core\_2.10. **1.5.1**
- org.elasticsearchsearch.elasticsearch-spark\_2.10. **2.1.0.Beta1**
- org.scalatest.scalatest\_2.10. **2.2.3**

If I try to use anything higher than elasticsearch-spark\_2.10. **2.1.0.Beta1** , I get the error in the below.

What are the right dependencies if I want to run:

- Apache Spark 1.5.1
- Elasticsearch 1.7.0
- on JDK 1.8.66

Thanks,

Likely at runtime you are using a mixture of Scala 2.11 and libraries compiled for Scala 2.10. Double check that indeed, all the jars are compiled for the same scala version (note that ES-Spark comes with binaries for both 2.10 and 2.11).
