Redesign the dfs namespace datastructures to be copy on write
-------------------------------------------------------------

         Key: HADOOP-334
         URL: http://issues.apache.org/jira/browse/HADOOP-334
     Project: Hadoop
        Type: Improvement

  Components: dfs  
    Versions: 0.4.0    
    Reporter: Owen O'Malley
 Assigned to: Owen O'Malley 


The namespace datastructures should be copy on write so that the namespace does not need to
be completely locked down from user changes while the checkpoint is being made.
