Jiayi-Liao opened a new pull request #13571:
URL: https://github.com/apache/flink/pull/13571
# What is the purpose of the change
Currently the error thrown from `runAsync()` method will be swallowed because Flink didn't handle all throwables with `AkkaRpcActor`. Here is a temporary fix for such cases in `YarnResourceManager`.
## Brief change log
* Use try-catch to wrap the runnable that was invoked in `runAsync()` method, and reuse the `FatalErrorHandler` to handle the error.
## Verifying this change
* Add a new unit test
## 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/Mesos, ZooKeeper: no
- 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

Sure that the thrown `RuntimeException` will trigger an` IllegalStateException`?

I think the test passes also w/o these lines. Can we make it explicit where the exception is thrown which is reported via the `TestingFatalErrorHandler`?
