Review request for hive and Xuefu Zhang.


Updated according to Xuefu's suggestions.

Bugs: HIVE-8278

Repository: hive-git


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.

Diffs (updated)
