> 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.
