-------------------------------
[~vvasudev], do we still want to do this ? otherwise, we can close it out
> Add support for web services to the WebApp proxy

> Key: YARN-1755
> URL: https://issues.apache.org/jira/browse/YARN-1755
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Varun Vasudev
>
> The RM currently has an inbuilt web proxy that is used to serve requests. The
> web proxy is necessary for security reasons which are described on the Apache
> Hadoop website
> (http://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/WebApplicationProxy.html).
> The web application proxy is a part of YARN and can be configured to run as
> a standalone proxy. Currently, the RM itself supports web services. Adding
> support for all the web service calls in the web app proxy allows it to
> support failover and retry for all web services. The changes involved are the
> following –
> a. Add support for web service calls to the RM web application proxy and
> have it make the equivalent RPC calls.
> b. Add support for failover and retry to the web application proxy. We can
> refactor a lot of the existing client code from the Yarn client.
