---------------------------------------

             Summary: API call to restart all components on one or more hosts 
should result in one request
                 Key: AMBARI-4791
                 URL: https://issues.apache.org/jira/browse/AMBARI-4791
             Project: Ambari
          Issue Type: Task
          Components: controller
    Affects Versions: 1.5.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 1.5.0


Currently, restarting all components (or all components that need config 
update) on a host (or multiple hosts) requires batching of multiple calls (one 
call per component type). This results in a whole bunch of requests being 
generated and floods the request history visible from the background operation 
popup.
Restart should work in a similar way as "Start" and "Stop" for host components, 
where the FE can construct a single API call that results in a single request.
