rkhachatryan opened a new pull request #13267:
URL: https://github.com/apache/flink/pull/13267
## What is the purpose of the change
Currently, `AsyncCheckpointRunnable` throws an exception if
`SubtaskCheckpointCoordinatorImpl` is closed.
However, it should also check its own status as it might be a normal case.
## Verifying this change
The change is covered by existing end-to-end tests which are currently
failing.
Unit testing would involve concurrency which I think would be overkill for
essentially a logging problem.

- Dependencies (does it add or upgrade a dependency): no
