Colin Patrick McCabe created HDFS-5676:
------------------------------------------

             Summary: fix inconsistent synchronization of CachingStrategy
                 Key: HDFS-5676
                 URL: https://issues.apache.org/jira/browse/HDFS-5676
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs-client
    Affects Versions: 2.4.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
            Priority: Minor


Currently, the synchronization for {{CachingStrategy}} is a little inconsistent.  DFSOutputStream#setDropBehind modifies the strategy object, but there's nothing protecting that object against concurrent use in {{createBlockOutputStream}}.  Similarly, {{DFSInputStream#setDropBehind}} is synchronized, but not all the uses of {{cachingStrategy}} are.
