Peter Cseh commented on OOZIE-2554:
-----------------------------------
We could do something similar we're doing in
[JavaActionExecutor.getLauncherClasses|https://github.com/apache/oozie/blob/master/core/src/main/java/org/apache/oozie/action/hadoop/JavaActionExecutor.java#L158].
The {{main}} function would be called using reflection or by defining to wrap
SparkMain.
There could be a property like {{oozie.action.spark.main.class}} with default
value {{org.apache.spark.SparkMain}} and we would replace SparkMain with a
validator during tests.
This way we won't call Spark in the tests, but we could test out that SparkMain
handles the properties as it should.
