[jira] [Created] (BEAM-341) ReduceFnRunner allows GC time overflow

Kenneth Knowles created BEAM-341:
------------------------------------

             Summary: ReduceFnRunner allows GC time overflow
                 Key: BEAM-341
                 URL: https://issues.apache.org/jira/browse/BEAM-341
             Project: Beam
          Issue Type: Bug
          Components: runner-core
            Reporter: Kenneth Knowles
            Assignee: Kenneth Knowles


In {{ReduceFnRunner}}, any window ending after the global window has its GC time capped to the end of the global window. But for windows ending before the global window the allowed lateness can still be arbitrary, causing overflow.
