> Why are the changes needed?
To avoid having a physical plan that is disconnected from the physical plan that is being executed. When a physical plan node executes a logical plan, the inner query is not connected to the running physical plan. The physical plan that actually runs is not visible through the Spark UI and its metrics are not exposed. In some cases, the EXPLAIN plan doesn't show it.
