[jira] [Created] (SPARK-2086) Improve output of toDebugString to make shuffle boundaries more clear

             Summary: Improve output of toDebugString to make shuffle boundaries more clear
                 Key: SPARK-2086
                 URL: https://issues.apache.org/jira/browse/SPARK-2086
             Project: Spark
          Issue Type: Improvement
            Reporter: Patrick Wendell
            Assignee: Gregory Owen
            Priority: Minor


It would be nice if the toDebugString method of an RDD did a better job of explaining where shuffle boundaries occur in the lineage graph. One way to do this would be to only indent the tree at a shuffle boundary instead of indenting it for every parent.
