--------------------------------------------------------
I suggest we do solution 1) to simply the implementation as the first step.
[~Paul Guo]
Since RPS will only be called by master and a query usually only raises several
RPS request, there won't be a lot of requests to RPS. So I think load balancer
may be over-design.
For services which support a lot of concurrent requests, a proxy server at the
front of multiple web Service is an ideal design, since it will be convenient
for both HA and load balance.

It's a good suggestion for auto-discover RPS failure and auto-restart, but I
think RPS is a little different from Resource Manager process. We need add
special processing for it since it's a Web service. Do you have any suggestion
on the detailed implementation?

> Once Ranger is configured, HAWQ will rely on RPS to connect to Ranger. A
> single point RPS may influence the robustness of HAWQ.
> Thus We need to investigate and design out the way to implement RPS High
> availability.
