> Improve Spark Debug RDD Graph

>                 URL:
>             Project: Hive
>          Issue Type: Sub-task

> 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.
