create(file, true) appears to be violating atomicity
----------------------------------------------------

                 Key: HDFS-1563
                 URL: https://issues.apache.org/jira/browse/HDFS-1563
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.20.1
            Reporter: Guanghao Shen
            Assignee: dhruba borthakur


Will upload a unittest to reveal this bug.

In a word, when a thread is doing create(file, true) on existing file, there are chances that
another thread will get 'false' for exists(file) during the period.
