> PORelationToExprProject currently uses "BagFactory.newDefaultBag()" to create
> an empty bag in cases where it has to send an empty bag on EOP - each such
> empty bag created will be registered with the SpillableMemoryManager as a
> spillable bag. Since it is an empty bag, it really should not be registered
> as a spillable bag. For this, NonSpillableDataBag can be used.
