kl0u opened a new pull request #10835: [FLINK-15533] Fix parallelism setting propagation during graph instantiation. URL: https://github.com/apache/flink/pull/10835 ## What is the purpose of the change Before the introduction of the executor (FLIP-73) and the consolidation of the different environments, some environments were overwriting the parallelism setting in their constructor. Now, after the refactoring of the environments we were not always doing it. In addition, the problem now is even more evident as that the user can directly pass a `Configuration` in the `(Stream)ExecutionEnvironment` constructor. This PR makes sure that we always expose a consistent view of the parallelism when the user calls `env.getParallelism()`. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
