Aaron Davidson created SPARK-4264:
-------------------------------------

             Summary: SQL HashJoin induces "refCnt = 0" error in ShuffleBlockFetcherIterator
                 Key: SPARK-4264
                 URL: https://issues.apache.org/jira/browse/SPARK-4264
             Project: Spark
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Aaron Davidson
            Assignee: Aaron Davidson
            Priority: Blocker


This is because it calls hasNext twice, which invokes the completion iterator twice, unintuitively.
