Would make this static and pass the options explictly.

Issue Time Tracking
-------------------
Worklog Id: (was: 145651)
Time Spent: 3h 10m (was: 3h)
> Add ability to stage directories with compiled classes to Spark
> ---------------------------------------------------------------
>
> Key: BEAM-3371
> URL: https://issues.apache.org/jira/browse/BEAM-3371
> Project: Beam
> Issue Type: Sub-task
> Components: runner-spark
> Reporter: Lukasz Gajowy
> Assignee: Jean-Baptiste Onofré
> Priority: Minor
> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> This one is basically the same issue as
> [this Flink's one|https://issues.apache.org/jira/browse/BEAM-3370], except
> of two things:
> - a detection of files to stage has to be provided in Spark, which is already
> being developed [here|https://issues.apache.org/jira/browse/BEAM-981]
> - the test execution is not interrupted by FileNotFoundException but by *the
> effect* of the directory not being staged (absence of test classes on the
> Spark's classpath, hence ClassNotFoundException).
> Again, this probably could be resolved analogously as in flink, while
> BEAM-981 issue is resolved.
