Jeffrey E Rodriguez updated HDFS-11502:
----------------------------------------
Description:
Datanode UI calls "dn.js" which loads properties for datanode. "dn.js" sets
"data.dn.HostName" datanode UI to "window.location.hostname", it should use a
datanode property from jmx beans or an appropriate property. The issue is
that if we use a proxy to access datanode UI we would show proxy hostanme
instead of actual datanode hostname.
I am proposing using Hadoop:service=DataNode,name=JvmMetrics" tag.Hostname
field to do that.
was:
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.
