             Summary: Reshuffle may set watermark holds past the end of time
                 Key: BEAM-2259
                 URL: https://issues.apache.org/jira/browse/BEAM-2259
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Thomas Groh
            Assignee: Thomas Groh


When it does so, the ReduceFnRunner throws an exception that the watermark hold is past the end of time

This affects all non-Dataflow runners.
