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

             Summary: Fetch up to max bytes when buf really released
                 Key: SPARK-21956
                 URL: https://issues.apache.org/jira/browse/SPARK-21956
             Project: Spark
          Issue Type: Improvement
          Components: Shuffle, Spark Core
    Affects Versions: 2.1.0
            Reporter: zhoukang


Right now,ShuffleBlockFetcherIterator will decrease bytesInFlight immediatily when take from results queue.But currentresult's bytebuf has not been released at that time.Then direct memory may be a little out of control.
We should decrease bytesInFlight when currentresult's bytebuf really been released.
