API + restart the services that restart is required

after adding new parameter and value to the ambari cluster , we need to restart the service to take affect

from ambari GUI restart the service is required , and we can see that because restart button is colored with orange

so my question is

we need API command that restart only the services that restart is required?

Solution

  • in order to restart all relevant services ( that need's restart ) the following syntax is the answer

    curl  -u admin:admin -H "X-Requested-By: ambari" -X POST  -d '{"RequestInfo":{"command":"RESTART","context":"Restart all required services","operation_level":"host_component"},"Requests/resource_filters":[{"hosts_predicate":"HostRoles/stale_configs=true"}]}' http://amb25101.example.com:8080/api/v1/clusters/plain_ambari/requests
