[jira] [Created] (BEAM-5211) Flink Streaming ExecutableStage operator chain blocks grpc receiver threads

Thomas Weise created BEAM-5211:
----------------------------------

             Summary: Flink Streaming ExecutableStage operator chain blocks grpc receiver threads 
                 Key: BEAM-5211
                 URL: https://issues.apache.org/jira/browse/BEAM-5211
             Project: Beam
          Issue Type: Bug
          Components: runner-flink
    Affects Versions: 2.6.0
            Reporter: Thomas Weise
            Assignee: Thomas Weise
             Fix For: 2.7.0


The operator attempts to emit results as they are received, within the grpc thread, while the subtask thread is waiting for bundle completion. This leads to blocking of grpc threads and eventually deadlock when multiple stages are within an operator chain. See attached stacktrace.
