---------------------------------------------
Thanks I would do so
> dn.js set datanode UI to window.location.hostname, it should use jmx
> "qry=Hadoop:service=DataNode,name=RpcDetailedActivityForPort8010" to get
> tag.hostname

> Key: HDFS-11502
> URL: https://issues.apache.org/jira/browse/HDFS-11502
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs
> Affects Versions: 2.7.2, 2.7.3
> Environment: all
> Reporter: Jeffrey E Rodriguez
>
> 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.
