> NetworkTopologyImpl.sortByDistanceCost currently sort only by distance. It
> should also account for racks, i.e. datanodes in the same rack should be next
> to each other.
> || Racks || Client/Datanodes ||
> | R1 | Client |
> | R2 | Dn1, Dn2 |
> | R3 | Dn3 |
> In the example above, the distances are the same so the current code may
> return Dn1, Dn3, Dn2. Then the Client may stream Dn1 -> Dn3 -> Dn2 which
> unnecessarily crossing the racks one more time.
