Provide dfsadmin functionality to report on namenode's view of network topology
-------------------------------------------------------------------------------

                 Key: HADOOP-5258
                 URL: https://issues.apache.org/jira/browse/HADOOP-5258
             Project: Hadoop Core
          Issue Type: New Feature
            Reporter: Jakob Homan
            Assignee: Jakob Homan


As discussed in HADOOP-4954, it would be useful to be able to query the namenode to its current
view on the network topology of racks and datanodes.  This would allow ops to compare what
the namenode sees with what they expect it to see.
