-------------------------------------------

             Summary: 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: 2.7.3, 2.7.2
         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.
