### Describe the issue this Pull Request addresses CDC image loading allocates spillable maps that were not closed when iterator creation or traversal failed, leaking disk and native resources. The LOG_FILE path also allocated a spillable map for an absent before-slice even though that cache remains empty. ### Summary and Changelog - Close newly allocated CDC image maps when loading or cache registration fails, preserving cleanup failures as suppressed exceptions. - Generalize image-record helpers to the `Map` interface and use `Collections.emptyMap()` when no before-image slice exists. - Ensure the log-record iterator and image manager are both closed while preserving the primary close failure. - Add focused coverage for iterator-creation and iteration failure cleanup. ### Impact Prevents temporary disk and native resource leaks in Flink CDC reads. There are no public API, configuration, storage-format, or user-visible behavior changes. ### Risk Level Low. The changes are localized to Flink CDC image-cache lifecycle handling and are covered by focused unit tests. ### 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.
