NicoK opened a new pull request #6470: [FLINK-10006][network] improve logging in BarrierBuffer: prepend owning task name URL: https://github.com/apache/flink/pull/6470 ## What is the purpose of the change Almost all log messages of `BarrierBuffer` do not contain the task name and are therefore of little use if either multiple slots are executed on a single TM or multiple checkpoints run in parallel. Please also merge to `release-1.6` and `master`. ## Brief change log - prepend the owning task name to `BarrierBuffer` log messages (available from the `InputGate`) - add task name to `SingleInputGate` logs ## Verifying this change This change is a trivial rework / code cleanup without any test coverage. - Tested manually the log messages with logging level set to `DEBUG` and the `SocketWindowWordCount` with checkpointing and parallelism 4. ## 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, 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**
