cloud-fan opened a new pull request, #43836: URL: https://github.com/apache/spark/pull/43836
backport https://github.com/apache/spark/pull/43797 ### What changes were proposed in this pull request? GROUP BY ordinal is not idempotent today. If the ordinal points to another integer literal and the plan get analyzed again, we will re-do the ordinal resolution which can lead to wrong result or index out-of-bound error. This PR fixes it by using a hack: if the ordinal points to another integer literal, don't replace the ordinal. ### Why are the changes needed? For advanced users or Spark plugins, they may manipulate the logical plans directly. We need to make the framework more reliable. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? new test ### Was this patch authored or co-authored using generative AI tooling? no -- This is an automated message from the Apache Git Service.
