   Meta comment: moving this to the driver has potential for destabilizing the application.
   In SPARK-36419, we added option to move the final `treeAggregate` to executor given the scale challenges seen.
   
   One option would be to do this in an executor as @zhengruifeng suggested, and that should be much more scalable as a solution.
