That was actually our approach

 You have to keep polling for the request id until it completes.
curl -X POST -u admin:admin -H 'X-Requested-By:1'
-d '{"RequestInfo":{"context":"YARN Service Check","command":"YARN_SERVICE_CHECK"},"Requests/resource_filters":[{"service_name":"YARN"}]}'
{  "href" : "",  "Requests"
: {    "id" : 12,    "status" : "Accepted"  }}%

curl -X GET -u admin:admin -H 'X-Requested-By:1'
| grep request_status    "request_status" : "COMPLETED",

Subject: REST API operations completed

Hi all,

Is there a backend way to be notified when an Ambari operation (such as running a service
check or restart) has finished?
Or is there a way to run a service check from the backend using REST API command, but it returns
the result of the service check only after it completes?

When using REST API command to run a service check, we are instantly given info regarding
that service check, instead of receiving that info after it completes.

Other then constantly checking that request using a REST API command, is there a way to know
when the Ambari operation has completed?

Thanks for your time
