> While looking into writing some tests for skipped stages (SPARK-10192), I realized that we might be able to eliminate skipped stages completely.  This would be great, since they are a source of confusion for end users, and are also confusing even for developers and lead to bugs like SPARK-9809.
> I'm not totally sure yet this will even be possible -- perhaps there will be some unintended consequences I haven't thought of yet, but I will give it a shot.
