> Currently when running in Standalone mode, Spark UI's link to workers and application drivers are pointing to internal/protected network endpoints. So to access workers/application UI user's machine has to connect to VPN or need to have access to internal network directly.
> Therefore the proposal is to make Spark master UI reverse proxy this information back to the user. So only Spark master UI needs to be opened up to internet. 
> The minimal changes can be done by adding another route e.g. http://spark-master.com/target/<endpoint>/ so when request goes to target, ProxyServlet kicks in and takes the <endpoint> and forwards the request to it and send response back to user.
> More information about discussions for this features can be found on this mailing list thread http://apache-spark-developers-list.1001551.n3.nabble.com/spark-on-kubernetes-tc17599.html
