             Summary: Test for fetch failure in a shared dependency for "skipped" stages
                 Key: SPARK-10192
                 URL: https://issues.apache.org/jira/browse/SPARK-10192
             Project: Spark
          Issue Type: Test
          Components: Spark Core
            Reporter: Imran Rashid
            Assignee: Imran Rashid


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.
