Liang-Chi Hsieh 3f7780d30d [SPARK-32136][SQL] NormalizeFloatingNumbers should work on null struct ... ### What changes were proposed in this pull request? This patch fixes wrong groupBy result if the grouping key is a null-value struct. ### Why are the changes needed? `NormalizeFloatingNumbers` reconstructs a struct if input expression is StructType. If the input struct is null, it will reconstruct a struct with null-value fields, instead of null. ### Does this PR introduce _any_ user-facing change? Yes, fixing incorrect groupBy result. ### How was this patch tested? Unit test. Closes #28962 from viirya/SPARK-32136.
