Date Sun, 05 Feb 2017 09:28:41 GMT
Aviem Zur created BEAM-1392:

             Summary: DoFn teardown not called on empty partitions
                 Key: BEAM-1392
             Project: Beam
          Issue Type: Bug
          Components: runner-spark
            Reporter: Aviem Zur
            Assignee: Aviem Zur

DoFn teardown is not called on empty partitions.

Discovered in a long running Kafka pipeline (read from Kafka -> write to Kafka) where some
partitions did not have data and Kafka producers where being created but not closed, eventually
resulting in {{Too many open files}} exception.
