Raghu Angadi commented on HADOOP-1185:
--------------------------------------
Looks good.
The code sets <form action> to request url that server sees. This won't work if
the server is behind a (server side) proxy. You can just remove 'action'
attribute and the browser defaults to current url (that browser sees, which is
what you really want).

> I would like to switch on the debug log level of the namenode without
