we have ambari cluster and HDP version 2.6.5
we want to add the service OOZIE on specific nodes in our cluster
for example - we have 10 workers machines in the HDP cluster
so we want to add he service OOZIE on each worker machine
from documentation we found the following API that really add the service to ambari
curl --user admin:admin -H "X-Requested-By: ambari" -i -X POST -d '{"ServiceInfo":{"service_name":"OOZIE"}}' http://localhost:8080/api/v1/clusters/HDP/services
but we not succeeded to improve the API in order to install the service OOZIE on each worker node
the final target is to add the service to amabri while each worker node in amabri should have the service OOZIE
any ideas how to continue from this stage?

Follow the below steps to install Oozie through api
- Add service component:
# curl -u admin:<password> -iv -H 'X-Requested-By: ambari' -X POST http://<Ambari Host>:<Port>/api/v1/clusters/<Cluster Name>/services/OOZIE/components/OOZIE_SERVER
# curl -u admin:<password> -iv -H 'X-Requested-By: ambari' -X POST http://<Ambari Host>:<Port>/api/v1/clusters/<Cluster Name>/services/OOZIE/components/OOZIE_CLIENT
- Add host component:
# curl -u admin:<password> -iv -H 'X-Requested-By:ambari' -i -X POST -d '{'host_components' : [{'HostRoles':{'component_name':'OOZIE_CLIENT'}}] }' http://<Ambari Host>:<Port>/api/v1/clusters/<Cluster Name>/hosts?Hosts/host_name=<HOST NAME>
# curl -u admin:<password> -iv -H 'X-Requested-By:ambari' -i -X POST -d '{'host_components' : [{'HostRoles':{'component_name':'OOZIE_SERVER'}}] }' http://<Ambari Host>:<Port>/api/v1/clusters/<Cluster Name>/hosts?Hosts/host_name=<HOST NAME>
- Install service:
# curl -u admin:<password> -iv -H 'X-Requested-By: ambari' -X PUT -d '{'ServiceInfo': {'state' : 'INSTALLED'}}' http://<Ambari Host>:<Port>/api/v1/clusters/<Cluster name>/services/OOZIE
