Description

If a SideOutputDataStream is used in `execute_and_collect`, `from_data_stream`, `create_temporary_view`, the side-outputing operator will not be properly configured, since we rely on the bottom-up scan of transformations while there's no solid transformation after the SideOutputTransformation in these cases. Thus, an error, "tuple object has no attribute get_fields_by_names", will be raised.
