Haohui Mai commented on HDFS-5333:
----------------------------------
The browser accesses the page, and the input from JMX directly. The HTTP
requests look like the following:
{noformat}
http://<namenode-http-server>/static/hadoop.css
http://<namenode-http-server>/dfshealth.html
http://<namenode-http-server>/jmx/foobar
{noformat}
The HTTP requests of accessing the old web UI look like the following:
{noformat}
http://<namenode-http-server>/dfshealth.jsp
http://<namenode-http-server>/static/hadoop.css
{noformat}
Therefore:
* You can access the new web UI if you can access the old one, regardless to
the settings of the port-based firewall.
* If you access the old web UI through a proxy, the set up for the new web UI
is similar.
Hope that answers your question.
