rdblue commented on issue #23836: [SPARK-26915][SQL] DataFrameWriter.save() should write without schema validation URL: https://github.com/apache/spark/pull/23836#issuecomment-465259581 @jose-torres, SaveMode is used by v1. That is the best way to ensure that queries don't break. SaveMode should be translated to concrete plans for v2. Otherwise, v2 is just as unpredictable as v1 and we don't gain anything.
