      Description

      HDFS-5215 changed the DataNode volume available space calculation to consider the reserved space held by the dfs.datanode.du.reserved configuration property. As a side effect, reserved space is now counted towards non-DFS used. I don't believe it was intentional to change the definition of non-DFS used. This issue proposes restoring the prior behavior: do not count reserved space towards non-DFS used.
