stevomitric opened a new pull request, #46974: URL: https://github.com/apache/spark/pull/46974
### What changes were proposed in this pull request? In this PR, rule `InsertMapSortInGroupingExpressions` was modified to add an alias for `map_sort(col)` . Grouping and aggregate expressions are then modified to use this alias. ### Why are the changes needed? Currently, trying to reference a map column that is being grouped by, causes reference errors because we are only replacing the grouping expression `m` with `map_sort(m)`. The following query fails: ```sql SELECT m FROM table GROUP BY m ``` ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? New Tests in this PR, and existing tests regarding grouping of map types. ### Was this patch authored or co-authored using generative AI tooling?
