> SHS supports Knox gateway by setting {{spark.ui.proxyBase}} to the proper value. The
main problem with this approach is that when {{spark.ui.proxyBase}} is set, SHS is not accessible
anymore through direct access.
> Since Knox provides in the header {{X-Forwarded-Context}} the base URL to use (there
is a patch available in KNOX-1295), we can leverage it in order to dynamically retrieve the
right proxy base, instead of relying on a fixed config. In this way, both access via Knox
proxy and via direct URL can work properly.
