I tried to modify PhysicalOperation's collectProjectsAndFilters, Added an
match case:
```
case Project(fields, child: LeafNode) if
!fields.forall(_.deterministic) =>
val (_, filters, other, aliases) = collectProjectsAndFilters(child)
val substitutedFields =
fields.map(substitute(aliases)).asInstanceOf[Seq[NamedExpression]]
(Some(substitutedFields), filters, other,
collectAliases(substitutedFields))
```
the problem can be solved. but I'm not sure if it will cause other
problems. Do you have any suggestions for that? thanks.
