Review comment:
+1 for adding a warning message here, I feel previous behavior with
silently exiting query might be quite confusing for users and developers.
nit: as we could have multiple `INSERT OVERWRITE` in one query, do we also
want to include table name (`table.identifier.table`) in warning message?
