> In Ambari UI we keep polling for last 10 requests, and *all* details about each request. 
> {code}
> http://server:8080/api/v1/clusters/ga/requests?to=end&page_size=10&fields=*,tasks/Tasks/*
> {code}
> On a 600 node cluster if you restart all services, this will contain MBs of data.
> We do not need so much data just to show the number of operations. We need to request API changes to provide rollup of tasks information into each request, and use that.
> The polling query should look more like:
> {code}
> http://server:8080/api/v1/clusters/ga/requests?to=end&page_size=10
> {code}
> This should provide the following about request - 
> * progress%
> * completed (yes/no)
> * state (success/warn/failure/timeout)
> Users should open the background-operations dialog and see progress of requests without making any further calls. Only when the user clicks on a request, should another call to get all tasks information be done.
