How can I stop the entire HDP stack via the CLI?

slm — Tue, 29 Dec 2015 03:08:48 GMT

How can I stop the entire HDP stack of services from the CLI? I seem to recall that there was a command to accomplish this but I can not find it. It would seem like this facility would be associated with the ambari-agent service but I did not see any such method/action on the usage for this script/service.

@Sam Mingolelli I am not sure if there was ever any single CLI command to stop entire HDP stack. But you can use Ambari APIs to start or stop all services. Refer below for the same.

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"):

  "Requests" : {
    "id" : 42,
    "status" : "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

    "task_count" : 16,
    "timed_out_task_count" : 0,
    "type" : "INTERNAL_REQUEST"
  },
...
...

When it says COMPLETED, the shutdown is done.

@Sam Mingolelli See this https://gist.github.com/randerzander/5b7b0e075e59f87d3c84

This is much better approach ..Thanks to @Randy Gelhausen
