[jira] [Created] (BEAM-1657) DirectRunner should not call close twice in UnboundedSourceExecutorFactory

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

             Summary: DirectRunner should not call close twice in UnboundedSourceExecutorFactory
                 Key: BEAM-1657
                 URL: https://issues.apache.org/jira/browse/BEAM-1657
             Project: Beam
          Issue Type: Bug
          Components: runner-direct
            Reporter: Ben Chambers
            Assignee: Thomas Groh


At the end of the processElement, in `finishRead` there is a 5% chance we decide to `close` the reader. If that happens, it will null-out the reader in the returned shard. But then the end of the `processElement` call will attempt too `close` the reader again, violating the spec.
