dhruba borthakur commented on HADOOP-4567:
------------------------------------------
Thanks for the review comments. I made it a separate variable so that the API
clearly identifies the hostname and the network topology.
>Having a separate racks variable implies that there is an implicit requirement
>that the the ordering of hosts and the racks are identical (which is true in
>this case
I missed your point. Can you pl explain it in greater detal? Thanks.
> GetFileBlockLocations should return the NetworkTopology information of the
> machines that hosts those blocks
