    Description

      I'm trying to refactor some name node classes, which seem to be similar.
      So DatanodeInfo is a public api now for purely external ( to name node) use.
      The name node class that stores information about data nodes including the
      set of its blocks is called DatanodeDescriptor.
      The DatanodeReport is removed since it was a variation of DatanodeInfo.
      Previously DatanodeInfo and DatanodeDescriptor were the same class, and
      DatanodeReport was used for reporting node statistics only.
      This is a preparation step for HADOOP-306.
