@samarth srivastava Just in case if you're looking for the API to restart required services after some configuration chnages, You can use a GET call to find out the components to be restarted. http://${AMBARI_HOST}:8080/api/v1/clusters/${CLUSTER_NAME}/host_components?HostRoles/stale_configs=true And if a list of components to be restarted is returned, you can invoke a POST request with a request body as below: http://${AMBARI_HOST}:8080/api/v1/clusters/${CLUSTER_NAME}/requests Request body: {
"RequestInfo": {
"command": "RESTART",
"context": "Restart all required services",
"operation_level": "host_component"
},
"Requests/resource_filters": [{
"hosts_predicate": "HostRoles/stale_configs=true"
}]
}
Note: This API works with Ambari version 2.4+ only.
