You can use a script like this to perform the shutdown of a cluster. The script below will first determine the cluster's name and then use it in subsequent calls to the API. USER=admin
PASSWORD=admin
AMBARI_HOST=localhost
#detect name of cluster
CLUSTER=$(curl -s -u $USER:$PASSWORD -i -H 'X-Requested-By: ambari' \
http://$AMBARI_HOST:8080/api/v1/clusters | \
sed -n 's/.*"cluster_name" : "\([^\"]*\)".*/\1/p')
#stop all services
curl -u $USER:$PASSWORD -i -H 'X-Requested-By: ambari' -X PUT \
-d '{"RequestInfo":{"context":"_PARSE_.STOP.ALL_SERVICES","operation_level":{"level":"CLUSTER","cluster_name":"Sandbox"}},"Body":{"ServiceInfo":{"state":"INSTALLED"}}}' \
http://$AMBARI_HOST:8080/api/v1/clusters/$CLUSTER/services
#start all services
curl -u $USER:$PASSWORD -i -H 'X-Requested-By: ambari' -X PUT \
-d '{"RequestInfo":{"context":"_PARSE_.START.ALL_SERVICES","operation_level":{"level":"CLUSTER","cluster_name":"Sandbox"}},"Body":{"ServiceInfo":{"state":"STARTED"}}}' \
http://$AMBARI_HOST:8080/api/v1/clusters/$CLUSTER/service When you run the above you'll see a response from the API like so (NOTE: here my cluster is called "dev09_ost_hivetest_h"): HTTP/1.1 202 Accepted

You can take the request ID ("id": 42) and monitor it to see if it's completed. $ curl -s -u admin:admin -i -H 'X-Requested-By: ambari' http://localhost:8080/api/v1/clusters/dev09_ost_hivetest_h/requests/42
