----------------------------------
Currently I am not able to view any data on the exposed endpoints. I get a
success 200 with Operational Menu options.
Is there any config to enable the endpoints ?

> Project: Apache Lens
> Issue Type: Improvement
> Components: server
> Reporter: Amareshwari Sriramadasu
> Assignee: Yash Sharma
> Priority: Critical
> Labels: newbie
> Fix For: 2.2

>
> We should provide a way to know LensService's health.
> Right now we have rest end points for /queryapi, /metastore which simply
> returns service is up or not. It is not much useful, for ex: QuerySubmitter
> has died on the server, there is no way to know.
> We have another end point exposed /admin/healthstatus - which is not
> implemented right now. we can use this to report more status about how each
> service doing - is anything down/ is it loaded and so on.
