NameNode should report status and performance for each replica of image and log
-------------------------------------------------------------------------------

                 Key: HADOOP-4029
                 URL: https://issues.apache.org/jira/browse/HADOOP-4029
             Project: Hadoop Core
          Issue Type: New Feature
          Components: dfs
    Affects Versions: 0.18.0
            Reporter: Robert Chansler


The administrator should have immediate access to the status of each replica. In addition
to reporting whether the replica is active or not, measured performance should be reported
so as to indicate whether a replica might impact cluster performance or might be in danger
of failing.

We're probably not close to doing automated replica fail over, but we can give the administrator
some clues.
