Review comment:
Original operator tree shape is changed when going through physical
transformations and task generation (don't know why though), as a result this
operator tree can not be used later to regenerate tasks or re-running physical
transformations. Therefore we make a copy and cache it after operator tree is
generated.
I will leave a comment.
