Subject Re: Classpath hell and Elasticsearch 2.3.2...
Date Thu, 02 Jun 2016 22:45:24 GMT
Hey there

When I used es-hadoop, I just pulled in the dependency into my pom.xml,
with spark as a "provided" dependency, and built a fat jar with assembly.

Then with spark-submit use the --jars option to include your assembly jar
(IIRC I sometimes also needed to use --driver-classpath too, but perhaps
not with recent Spark versions).
