What is the best way to include a class path that points to a JAR file when using the spark shell (specifically when running spark shell from the master of a multi slave master/slave cluster)? Or more specifically, the elasticsearch-hadoop jar compiled jar download: [http://www.elasticsearch.org/overview/hadoop/download/](http://www.elasticsearch.org/overview/hadoop/download/) more info: [http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/spark.html](http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/spark.html) elasticsearch-hadoop needs to be available in Spark’s classpath. As Spark has multiple deployment modes, this can translate to the target classpath, whether it is on only one node (as is the case with the local mode - which will be used through-out the documentation) or per-node depending on the desired infrastructure. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Also - does the elasticsearch-hadoop JAR need to be on all slave nodes too?
