> For applications (zeppelin & livy ) that use both pyspark and sparkr, we have 
> to duplicate the code in SparkSubmit to figure the where is the requirement 
> resources for pyspark & sparkr (pyspark.zip, py4j, sparkr.zip and R file in 
> jars). It would be better to provide option spark.usePython and spark.useR, 
> so that downstream project which use both pyspark and sparkr in one spark 
> application don't need to duplicate the code in SparkSubmit, can just 
> leverage these 2 options.
