Knox WebUI can't show dynamic contents

Hi All,I can't view the full UI (i.e. Namenode or Yarn UI) in browser. I can only see a static page -- no dynamic content though.
I found one potential error. In browser, I saw few files download were getting "404". When I saw it closely the failure downloads has wrong paths. For example.
1. Successful:  This file has succeeded with 200 : "http://MY_KNOX_HOST:8445/gateway/sandbox/hdfs/static/jquery-1.10.2.min.js" 
2. Failure: This one got 404. http://MY_KNOX_HOST:8445/static/jquery.dataTables.min.js 
If you closely see the failure case, the full path is not there. /gateway/sandbox/hdfs/ is missing. Btw I can see a few 404s.
Any idea? Or there could be something else?
Regards,Mohammad

You should be able to just update the rewrite.xml file and the touch the
topology file that has the reference to to the HDFSUI service.
Knox picks up topology file changes dynamically.
No need to restart the server.

I agree. Wandering if we could put a default rule of just pre-appending base path something "{$frontend[url]}/hdfs". Btw, what is the quickest of testing the rewrite.xml updates. Do I need to rebuild the package and install?Or I can go to the existing gateway installation and modify it "./data/services/hdfsui/2.7.0/rewrite.xml" and restart the server.
Do I need to use "knoxcli.sh redeploy" also?

For proxying resources, Web UIs are much more of a moving target than REST
