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

             Summary: HadoopOutputFormatBase should expose CLOSE_MUTEX for subuclasses
                 Key: FLINK-3147
                 URL: https://issues.apache.org/jira/browse/FLINK-3147
             Project: Flink
          Issue Type: Improvement
            Reporter: Nick Dimiduk
            Priority: Minor


While adopting PhoenixOutputFormat to a streaming job, I find that the implementation of {{HadoopOutputFormatBase#close}} is not relevant when there's no temp file to move. However, subclasses cannot effectively override implementation because {{CLOSE_MUTEX}} is marked private.
