chenhao-db opened a new pull request, #50121: URL: https://github.com/apache/spark/pull/50121
### What changes were proposed in this pull request? There is a bug in the initial optimizer rule that the `output` of the relation will be rebuilt based on the schema of the `HadoopFsRelation`. This schema doesn't include file metadata (the `_metadata` column). This PR fixes the bug. The new implementation no longer requires `hadoopFsRelation.schema` and `relation.output` to have the same order, which I don't think is guaranteed. ### Why are the changes needed? It is a necessary bug fix. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Unit test. It would fail without the fix. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
