Yiqun Lin commented on HDFS-11998:
----------------------------------

Hi [~vagarychen], thanks for filing this. In the next patch, please don't forget updating
the default value in class {{DFSConfigKeys.java}}.
{code}
  public static final String DFS_USE_DFS_NETWORK_TOPOLOGY_KEY =
      "dfs.use.dfs.network.topology";
  public static final boolean DFS_USE_DFS_NETWORK_TOPOLOGY_DEFAULT = false;
{code}

> 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!
