dhruba borthakur commented on HADOOP-4567:
------------------------------------------
Got it. Actually the queston you are raising is whether
BlockLocation.getTopologyPaths() should return /r1 or should it return /r1/h1.
I would prefer that this new method return /r1/h1. If somebody wants only the
hostname, they can continue to use the existing method
BlockLocation.getHostName().
> GetFileBlockLocations should return the NetworkTopology information of the
> machines that hosts those blocks
