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.
