Hi,

I'm trying to use elasticsearch-hadoop in Spark 1.6 (right now It's the only avaible version in our CDH cluster) and I'm having issues with `java.lang.ClassNotFoundException` using the main jar `elasticsearch-hadoop-6.5.4.jar`.

From the [documentation](https://www.elastic.co/guide/en/elasticsearch/hadoop/current/requirements.html#requirements-spark-sql) I'm supposed to use a separate jar `elasticsearch-spark-1.x-<version>.jar`, but I can't find it.

In the zip from the official download page there are these jars:

```auto
elasticsearch-hadoop-6.5.4.jar
elasticsearch-hadoop-cascading-6.5.4.jar
elasticsearch-hadoop-hive-6.5.4.jar
elasticsearch-hadoop-mr-6.5.4.jar
elasticsearch-hadoop-pig-6.5.4.jar
elasticsearch-spark-20_2.11-6.5.4.jar
elasticsearch-storm-6.5.4.jar

```

The spark jar is the one for Spark 2.x...

Thanks,  
Enrico

You should be able to get that artifact from maven. We publish two 1.3-1.6 compatibility jars there depending on your scala major version:

For Scala 2.10 you can find the available versions and artifact names here:  
[http://repo1.maven.org/maven2/org/elasticsearch/elasticsearch-spark-13\_2.10/](http://repo1.maven.org/maven2/org/elasticsearch/elasticsearch-spark-13_2.10/)

For Scala 2.11 you can find the available versions and artifact names here:  
[http://repo1.maven.org/maven2/org/elasticsearch/elasticsearch-spark-13\_2.11/](http://repo1.maven.org/maven2/org/elasticsearch/elasticsearch-spark-13_2.11/)
