 curl -u admin:admin -i -H 'X-Requested-By: ambari' -X PUT -d '{"HostRoles": {"state": "INSTALLED"}}' http://node2:8080/api/v1/clusters/HDP/hosts/node1/host_components/SPARK2_THRIFTSERVER

If your earlier API command was like below

curl -u admin:admin -i -H 'X-Requested-By: ambari' -X PUT -d '{"HostRoles": {"state": "INSTALLED"}}' http://node2:8080/api/v1/clusters/HDP/hosts/node1/host_components/SPARK2_THRIFTSERVER
HTTP/1.1 202 Accepted
.....
...
{
  "href" : "http://node2:8080/api/v1/clusters/HDP/requests/174",
  "Requests" : {
    "id" : 174,
    "status" : "Accepted"
  }

Then you should take note of the Request id i.e 174 in the above

curl -u admin:admin -i -H 'X-Requested-By: ambari' -X GET http://node2:8080/api/v1/clusters/HDP/requests/{174}

curl -u admin:admin -i -H 'X-Requested-By: ambari' -X GET http://node2:8080/api/v1/clusters/HDP/requests/{174}
