> Right now getDatanodeReport is being used in only two places in the HDFS 
> code: the Balancer and DFSAdmin. And it is the only reason for these classes 
> to use DFSClient. If we would move the method definition (or copy for now 
> deprecating the old location) to the NameNode protocol DFSAdmin and Balancer 
> will not rely on DFSClient anymore and will be cleaner. This will also help 
> the Balancer to run cleaner against HDFS-599 changes.
> Thoughts?
