> In SparkMain we use the option {{--conf spark.driver.extraClassPath=}} to put
> together the jars needed for Spark. If the user specifies this option, Oozie
> appends to the value.
> If {{--driver-class-path}} is defined in {{<spark-opts>}} then it's value
> overwrites the other ones, causing the Spark action to fail.
> We should handle both ways to define classpaths the same.
