Zakelly opened a new pull request, #29392: URL: https://github.com/apache/flink/pull/29392
## What is the purpose of the change Fix the wierd implementation of `StreamOperatorStateHandler::dispose`, which register the `close` then `dispose` of each state backend but the actually the Guava's closer close things in a reverse order. It seems we should do `close` before `dispose`. ## Brief change log - Register cleanup actions so Guava `Closer` invokes `close()` before `dispose()`. - Close backends before disposal in `StateBackendTestBase` and remove redundant disposal. ## Verifying this change This change is already covered by existing tests, such as `StreamOperatorStateHandlerTest` and `StateBackendTestBase` subclasses, including RocksDB and Changelog backend tests. These commits have not been retested. ## 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 serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: yes — state backend cleanup - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? not applicable --- ##### Was generative AI tooling used to co-author this PR?
