HuangZhenQiu opened a new pull request, #19968: URL: https://github.com/apache/hudi/pull/19968
### Describe the issue this Pull Request addresses Adds a compactionErrorCount metric to FlinkCompactionMetrics so compaction failures - including ones swallowed by NonThrownExecutor when compaction runs asynchronously - become observable. ### Summary and Changelog - FlinkCompactionMetrics: add a Counter compactionErrorCount, register it in the metric group, and expose markCompactionFailed() to increment it. - DataTableCompactHandler: call markCompactionFailed() in the async executor's failure callback before emitting the failed commit event, so every async compaction failure is counted. - TestDataTableCompactHandler: add test coverage for the failure path. ### Impact none ### 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.
