> 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.
