brkyvz commented on issue #27391: [SPARK-30612][SQL] Resolve qualified column name with v2 tables URL: https://github.com/apache/spark/pull/27391#issuecomment-581237957 Agree with @cloud-fan. Please do not remove the old code in resolution for the following too reasons: 1. It's very risky to do so right now 2. # of qualifiers < 3 will still be the most common case. We should still have the proper resolution there. I think your matcher should come in if the first two qualifier matching code doesn't work.
