> HIVE-8249 greatly simply file the SparkPlan model and the SparkPlanGenerator
> logic. As a side effect, however, a visual representation of SparkPlan got
> lost. Such representation is helpful for debugging and performance profiling.
> In addition, it would be also good to separate plan generation and plan
> execution.
