> ------------------------
>
> Key: HADOOP-321
> URL: http://issues.apache.org/jira/browse/HADOOP-321
> Project: Hadoop
> Type: Improvement
> Components: dfs
> Reporter: Konstantin Shvachko
> Assignee: Konstantin Shvachko
> Fix For: 0.4.0
> Attachments: DatanodeInfo_refactor.patch
>
> 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.
