> It would be nice if HDFS provides a feature to store extended attributes for files, similar
to the one described here: http://en.wikipedia.org/wiki/Extended_file_attributes. 
> The challenge is that it has to be done in such a way that a site not using this feature
does not waste precious memory resources in the namenode.
