### Describe the issue this Pull Request addresses Closes https://github.com/apache/hudi/issues/18451 ### Summary and Changelog - Add guards to prevent non-Spark engines (Flink, Hive, Presto, Trino) from reading or writing Lance-format Hudi tables. Lance is Spark-only for 1.2. - Guards at multiple levels: - **Config-time (Flink)**: `HoodieTableFactory` rejects Lance on both source and sink; `HoodieHiveCatalog` rejects on table creation - **Read-time (Flink)**: `FlinkRowDataReaderContext` rejects Lance files - **Read-time (Hive)**: `HiveHoodieReaderContext` rejects Lance files early - **Factory-level (all engines)**: Base `HoodieFileReaderFactory` / `HoodieFileWriterFactory` throw for Lance; only Spark overrides to support it - Centralized error message `LANCE_SPARK_ONLY_ERROR_MSG` in `HoodieFileFormat` ### Impact Ensuring that for now users can only read/write lance base files with Spark until we add this support. ### Risk Level none ### Documentation Update none ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Enough context is provided in the sections above - [ ] Adequate tests were added if applicable -- This is an automated message from the Apache Git Service.
