-----------------------------------
Bulk update: moved all 3.4.0 non-blocker issues, please move back if it is a
blocker. Retarget 3.5.0.
> getBlockLocations RPC should use actual client ip to compute network distance
> when using RBF.

> Please correct me if i understand wrongly. Thanks.
> Currently, when a getBlockLocations RPC forwards to namenode via router.
> NameNode will use router ip address as client machine to compute network
> distance against block's locations. See FSNamesystem#sortLocatedBlocks method
> for more detailed information.
> I think this compute method is not correct and should use actual client ip.
