AlreadyBeingCreatedException detail message could contain more useful info
--------------------------------------------------------------------------

                 Key: HADOOP-978
                 URL: https://issues.apache.org/jira/browse/HADOOP-978
             Project: Hadoop
          Issue Type: Improvement
          Components: dfs
    Affects Versions: 0.11.0
            Reporter: Nigel Daley
            Priority: Minor


When I get this exception, it would be REALLY helpful if the detail message could include
the hostname of the host that is already creating the file.

org.apache.hadoop.dfs.AlreadyBeingCreatedException: failed to create file /user/foo/bar_02
for DFSClient_task_0001_m_001777_1 on client myhost.com becausependingCreates is non-null.
