Also, without this source code change, this test will fail because we don't have coverage for View. Hence, thought of writing it separately to cover all 4 cases together: add/delete and table/view. Hence, I think for `false` value of `ALLOW_SPLITTABLE_SYSTEM_CATALOG_ROLLBACK`, we don't need additional test :) Sounds good? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
