dongjoon-hyun commented on issue #25328: [SPARK-28595][SQL] explain should not trigger partition listing URL: https://github.com/apache/spark/pull/25328#issuecomment-517390551 I agree that it was very hard to meet the condition. BTW, IIRC, the main reason for that optimization was to get the same result with `Hive` for the `LIMIT` queries which didn't have `ORDER BY`. > I think it's worth to give up this optimization so that explain don't need to get stuck.
