> Datanode UI calls dn.js which loads properties for datanode..
> dn.js sets datanode UI to window.location.hostname, it should use jmx 
> "qry=Hadoop:service=DataNode,name=RpcDetailedActivityForPort8010" to get 
> tag.hostname.
> The issue is that if we proxy datanode UI we would get the proxy as the 
> hostname because UI code uses window.location.hostname instead of the actual 
> datanode hostname.
