> Make --py-files work in non pyspark application
> -----------------------------------------------
>
> Key: SPARK-24377
> URL: https://issues.apache.org/jira/browse/SPARK-24377
> Project: Spark
> Issue Type: Bug
> Components: Spark Submit
> Affects Versions: 2.3.0
> Reporter: Saisai Shao
> Priority: Minor
>
> For some Spark applications, though they're a java program, they require not
> only jar dependencies, but also python dependencies. One example is Livy
> remote SparkContext application, this application is actually a embedded REPL
> for Scala/Python/R, so it will not only load in jar dependencies, but also
> python and R deps.
> Currently for a Spark application, --py-files can only be worked for a
> pyspark application, so it will not be worked in the above case. So here
> propose to remove such restriction.
> Also we tested that "spark.submit.pyFiles" only supports quite limited
> scenario (client mode with local deps), so here also expand the usage of
> "spark.submit.pyFiles" to be alternative of --py-files.
