### Describe the issue this Pull Request addresses Closes https://github.com/apache/hudi/issues/20435. Partitioned record-index point lookups throw `ArithmeticException` when querying an empty partition and `NoSuchElementException` when the input key collection is empty. Both lookups should return no locations. ### Summary and Changelog - Return an empty result when no file slices match the requested data partition or the lookup key set is empty, before selecting a shard. - Preserve the existing metadata index availability checks and shard read failure propagation. - Add regression cases to the existing `TestHoodieBackedTableMetadataDataCleanup` class for empty lookups, unavailable metadata indexes, shard selection, and read failures. ### Impact Partitioned RLI point lookups handle empty partitions and empty key collections without throwing. No API or storage format changes. ### Risk Level Low. The change adds two early returns to the partition-scoped lookup path. Focused validation passed: 24 tests, zero failures/errors, and zero Checkstyle violations. ```bash mvn -B -pl hudi-common -am package -Dtest=TestHoodieBackedTableMetadataDataCleanup,TestHoodieBackedTableMetadataBuildPredicate -Dsurefire.failIfNoSpecifiedTests=false -Dsurefire.rerunFailingTestsCount=0 -DskipITs -DskipFTs ``` ### Documentation Update None. ### Contributor's checklist - [ ] 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
