featzhang opened a new pull request, #27715: URL: https://github.com/apache/flink/pull/27715
## What is the purpose of the change This PR adds a periodic expiration cleanup scheduler to `ResourceManager` that automatically removes expired entries from `NodeHealthManager` every 30 seconds. > **Note**: This PR depends on [#27714](https://github.com/apache/flink/pull/27714) ([FLINK-39176][runtime] Add configuration support for management blocklist). ## Brief change log - Add `healthCleanupFuture` field in `ResourceManager` to hold the scheduled task handle - In `startResourceManagerServices()`, schedule `nodeHealthManager.cleanupExpired()` at a fixed rate of 30 seconds using the existing `scheduledExecutorService` (no new thread pool created) - In `stopResourceManagerServices()`, cancel the scheduled future to prevent resource leaks ## Verifying this change This change is a purely internal scheduling mechanism. Verified by: - Manual code review confirming reuse of existing `ScheduledExecutorService` - Compilation passes with `mvn compile -pl flink-runtime -am -DskipTests` ## Does this pull request potentially affect one of the following parts - [ ] Dependencies (does it add or upgrade a dependency): **no** - [ ] The public API, i.e., is any changed class annotated with `@Public(Evolving)`: **no** - [ ] The serialization format, i.e., is any changed class annotated with `@Internal` and `Serializable`: **no** - [ ] The runtime per-record code paths (performance sensitive): **no** - [ ] Anything that affects deployment or recovery: **no** (cleanup only) - [ ] The S3 file system connector: **no** ## Documentation - Does this pull request introduce a new feature? **no** - If yes, how is the feature documented?
