lincoln-lil opened a new pull request, #21546: URL: https://github.com/apache/flink/pull/21546
## What is the purpose of the change There's an issue in AsyncWaitOperator that it not properly blocking retries when timeout occurs, reported by user ml https://lists.apache.org/thread/n1rqml8h9j8zkhxwc48rdvj7jrw2rjcy. This happens when a retry timer is unfired and then the user function timeout was triggered first, the current RetryableResultHandlerDelegator doesn't take the timeout process properly and will cause more unexpected retries. This pr aims to fix it. ## Brief change log Overwrite the timeout logic in RetryableResultHandlerDelegator and add guard for retryAwaiting flag to prevent unexpected retries. ## Verifying this change add case to current AsyncWaitOperatorTest ## 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: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
