reswqa opened a new pull request, #20912: URL: https://github.com/apache/flink/pull/20912
## What is the purpose of the change The parallel serialization introduced in [FLINK-26675](https://issues.apache.org/jira/browse/FLINK-26675) does not properly handle errors. StreamConfig#triggerSerializationAndReturnFuture returns a future that is never completed if the serialization fails, because all we do is throw an exception but that isn't propagated anywhere. As a result StreamingJobGraphGenerator#createJobGraph blocks indefinitely. ## Brief change log - *Propagate exception to the `serializationFuture` when a serialization exception is encountered.* ## Verifying this change Please make sure both new and modified tests in this PR follows the conventions defined in our code quality guide: https://flink.apache.org/contributing/code-style-and-quality-common.html#testing This change added two tests in `StreamingJobGraphGeneratorTest` verified the serialization exceptions of coordinator and streamConfig respectively. ## 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? no -- This is an automated message from the Apache Git Service.
