    Resolution: Not A Problem

I will deal with this in HDFS-1156

> 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.
