Review comment:
       Does it work when Spark is not installed in other nodes? IIRC, we can run the application in the cluster where Spark is not installed because the jars are shipped together in Yarn cluster.
   
   Likewise, PySpark was able to run. From my very cursory look, it's going to break this case because it will not distribute the local pyspark archive anymore. Can you confirm this @shanyu and @tgravescs?
