> As described in [HDFS-12200|https://issues.apache.org/jira/browse/HDFS-12200], ScriptBasedMapping
may lead to NN cpu 100%. ScriptBasedMapping run sub_processor to get rack info of DN/Client,
so we think  it's a little heavy.  We prepare to use TableMappingļ¼Œbut  TableMapping does
not support refresh and can not reload rack info of newly added DataNodes.
> So we implement refreshDNSToSwitch in dfsadmin.
