[jira] [Created] (HDFS-2708) Stats for the total # blocks and blocks per DN

Stats for the total # blocks and blocks per DN
----------------------------------------------

                 Key: HDFS-2708
                 URL: https://issues.apache.org/jira/browse/HDFS-2708
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node, name-node
            Reporter: Eli Collins
            Priority: Minor


It would be useful for tools to be able to retrieve the total # blocks in the file system (and also display eg via dfsadmin report, this is currently only available via FSNamesystemMetrics, so would add to ClientProtocol#getStats?) and the total number of blocks on each datanode (via DataNodeInfo).
