HyukjinKwon opened a new pull request, #58604: URL: https://github.com/apache/spark/pull/58604
### What changes were proposed in this pull request? Add `spark.sql.restrictedMode.enabled` (internal, default `false` = unchanged). When enabled, `reflect`/`java_method` and `TRANSFORM ... USING` are rejected during analysis with a new `UNSUPPORTED_FEATURE.SQL_RESTRICTED_MODE` error condition. `ADD JAR` / JAR-backed `CREATE FUNCTION` and the class-loading/URL JDBC data-source options are wired to the same flag but not yet gated (follow-up). ### Why are the changes needed? Provides an opt-in mode that disables dynamic code and external-script execution features in SQL for deployments that want a more constrained SQL surface. Off by default, so there is no behavior change unless enabled. ### Does this PR introduce _any_ user-facing change? No by default. When the mode is enabled, the listed features are rejected with a clear error. ### How was this patch tested? New `RestrictedModeSuite`: `reflect` and `TRANSFORM` are rejected when the mode is on and allowed when off. ### Was this patch authored or co-authored using generative AI tooling?
