SPARK: run using spark-submit on an existing cluster
--spark-master must be specified
--spark-submit-command may be specified to control the Spark submit command
arguments to spark-submit may optionally be specified after --
GCS: run using Google cloud dataproc
commands after the -- will be passed to dataproc
--cluster <your-cluster> must be specified after the --
spark properties and some common spark-submit parameters will be translated
to dataproc equivalents
--dry-run may be specified to output the generated command line without running it
--java-options 'OPTION1[ OPTION2=Y ... ]' optional - pass the given string of options to the
