> The network topology and dns to switch mapping are initialized at the start
> of the namenode.
> If admin wants to change the topology because of new datanodes added, he has
> to stop and restart namenode(s), otherwise those new added datanodes are
> squeezed under /default-rack.
> It is a low frequency operation, but it should be operated appropriately, so
> dfs admin should take the responsibility.
