> SPARK-17644 opened up a discussion about further refactoring of the
> DAGScheduler's handling of FetchFailure events. These include:
> * rewriting code and comments to improve readability
> * doing fetchFailedAttemptIds.add(stageAttemptId) even when
> disallowStageRetryForTest is true
> * issuing a ResubmitFailedStages event based on whether one is already
> enqueued for the current failed stage, not any prior failed stage
> * logging the resubmission of all failed stages
