cloud-fan commented on issue #24759: [SPARK-27395][SQL][WIP] Improve EXPLAIN command URL: https://github.com/apache/spark/pull/24759#issuecomment-521900642 cool thanks! We also need to discuss how to roll out this feature. It's a little aggressive to me to just replace the legacy explain format with the new one. For SQL, maybe we can use the new format for `EXPLAIN FORMATTED ...`. Currently `FORMATTED` is treated the same as `EXTENDED`, which is not very ideal. For Java/Scala, I don't have a good idea now. We don't even have `EXPLAIN COST` in Java/Scala API, maybe we can leave it for now.
