> We implemented eager shuffle cleanup in SPARK-47764. However, in queries with
> multiple layers of executions, shuffle dependencies for only the root
> execution is cleaned up.
> We should fix this and cleanup the shuffle dependencies for the child
> executions, based on the shuffle cleanup mode of the root execution.
