Shekharrajak opened a new pull request, #55826: URL: https://github.com/apache/spark/pull/55826
### What changes were proposed in this pull request? Add && path.eval() != null to the VariantGet case-arm guard in both collectRequestedFields and rewriteExpr in PushVariantIntoScan. ### Why are the changes needed? A VariantGet whose foldable path evaluates to null (e.g., variant_get(v, cast(null as string), 'int')) reaches PushVariantIntoScan when NullPropagation is excluded via spark.sql.optimizer.excludedRules. ### Does this PR introduce _any_ user-facing change? No. With the default optimizer pipeline (NullPropagation enabled), VariantGet(_, Literal(null), ...) is eliminated upstream — this code path was unreachable in practice. ### How was this patch tested? New unit tests in PushVariantIntoScanV1SuiteBase ### Was this patch authored or co-authored using generative AI tooling? Yes -- This is an automated message from the Apache Git Service.
