Daryn Sharp created HDFS-5514:
---------------------------------

             Summary: FSNamesystem's fsLock should allow custom implementation
                 Key: HDFS-5514
                 URL: https://issues.apache.org/jira/browse/HDFS-5514
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
    Affects Versions: 2.0.0-alpha, 3.0.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


Changing {{fsLock}} from a {{ReentrantReadWriteLock}} to an API compatible class that encapsulates
the rwLock will allow for more sophisticated locking implementations such as fine grain locking.
