> HDFS-11530 has made it configurable to use {{DFSNetworkTopology}}, and still
> uses {{NetworkTopology}} as default.
> Given the stress testing in HDFS-11923 which shows the correctness of
> DFSNetworkTopology, and the performance testing in HDFS-11535 which shows how
> DFSNetworkTopology can outperform NetworkTopology. I think we are at the
> point where I can and should enable DFSNetworkTopology as default.
> Any comments/thoughts are more than welcome!
