> Ning Li up on list has stated that getting blocks using hdfs though the block is local takes almost the same amount of time as accesing the block over the network.  See if can do something smarter when the data is known to be local short-circuiting hdfs if we can in a subclass of DFSClient (George Porter suggestion).
