----------------------------------

             Summary: Dataflow runner v2 tests occasionally fails with misconfigured sharding logic
                 Key: BEAM-11779
                 URL: https://issues.apache.org/jira/browse/BEAM-11779
             Project: Beam
          Issue Type: Bug
          Components: runner-dataflow
            Reporter: Yichi Zhang


Dataflow runner v2 test sometimes mysteriously fails data loss error message. This is due to misconfigured sharding logic from backend with combination of shuffle_mode=service and use_runner_v2 logic.

Example failing pipeline: https://pantheon.corp.google.com/dataflow/jobs/us-central1/2021-02-08_10_20_51-4474446822883759937?project=apache-beam-testing
