> The {{SparkPlan}} class does some logging to show the mapping between
> different {{SparkTran}}, what shuffle types are used, and what trans are
> cached. However, there is room for improvement.
> When debug logging is enabled the RDD graph is logged, but there isn't much
> information printed about each RDD.
> We should combine both of the graphs and improve them. We could even make the
> Spark Plan graph part of the {{EXPLAIN EXTENDED}} output.
> Ideally, the final graph shows a clear relationship between Tran objects,
> RDDs, and BaseWorks. Edge should include information about number of
> partitions, shuffle types, Spark operations used, etc.
