### Describe the issue this Pull Request addresses Memory leak in SqlQueryEqualityPreCommitValidator where cached Dataset objects are not being unpersisted after use, potentially causing memory pressure in long-running validation operations. ### Summary and Changelog This PR ensures cached Spark Dataset objects are properly unpersisted after use in validation queries. **Changes:** - Added try-finally block to guarantee unpersist() is called on cached datasets - Initialize prevRows and newRows to null before the try block for proper cleanup in case of exceptions - Ensures unpersist() is called even when validation fails or exceptions occur ### Impact Reduces memory consumption during pre-commit validation by properly releasing cached Spark datasets. No public API changes or user-facing feature changes. ### Risk Level **Low** - Defensive change that adds proper resource cleanup. The validation logic remains unchanged; only adds cleanup code to prevent memory leaks. ### Documentation Update none ### Contributor's checklist - [x] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [x] Enough context is provided in the sections above - [x] Adequate tests were added if applicable -- This is an automated message from the Apache Git Service.
