      Description

      One confusing corner case of the DAGScheduler is when there is a shared shuffle dependency, a job might "skip" the stage associated with that shuffle dependency, since its already been created as part of a different stage. This means if there is a fetch failure, the retry will technically happen as part of a different Stage instance.

      This already works, but is lacking tests, so I just plan on adding a simple test case.
