> There are two issues w/ Spark action's argument parsing within {{SparkMain}}
> h5. Driver and executor extra classpaths: equals sign used
> When the user specifies {{\-\-conf spark.executor.extraClassPath=XYZ}} or
> {{\-\-conf spark.driver.extraClassPath=ABC}}, the option {{\-\-conf}} will be
> added to {{sparkArgs}}. Then when the code tries to evaluate
> {{spark.executor.extraClassPath=XYZ}}, it uses special logic and set
> {{addToSparkArgs = false}}. As a result there will be a extra {{\-\-conf}} in
> the {{sparkArgs}} eventually.
> For example: {{\-\-conf spark.executor.extraClassPath=XYZ \-\-conf
> otherProperty=ABC}} will become {{\-\-conf \-\-conf otherProperty=ABC}},
> which will cause spark job submit failure later.
> We might need to remove one prior {{\-\-conf}} in {{sparkArgs}} if the
> current evaluated {{opt}} is {{EXECUTOR_CLASSPATH}} or {{DRIVER_CLASSPATH}}.
> h5. User provided files and archives: equals sign used
> For the following workflow XML snippet:
> {code:xml}
> <spark-opts>--files=${nameNode}/home/share/hive-site.xml --num-executors 4
> --executor-memory 7g --driver-memory 7g</spark-opts>
> {code}
> the {{\-\-files=$\{nameNode\}/home/share/hive-site.xml}} {{opt}} will be
> placed into {{sparkArgs}} in previous Oozie version without any modification,
> because we don't have special handling for {{\-\-files}} {{opt}}.
> If the user specifies {{\-\-files=$\{nameNode\}/home/share/hive-site.xml
> --num-executor 4}}, then {{SparkMain}} code treats {{\-\-num-executor}} as a
> file path / name. That caused the issue as I described in my previous
> comment. We might need to change the handling logic for {{FILES_OPTION}} and
> {{ARCHIVES_OPTION}} to be the same to {{DRIVER_CLASSPATH_OPTION}}.
