hi all

we have 3 masters machines ( master01 master02 master03 ) and on each master machine we have the relevant component

how to verify by API that all component on the specific master machine are stop?

for example we want to verify that all component on master01 are stoped

the API will return info (stop/start) about all componets that are run on master01

@Michael Bronson,

You can use the below curl call to get the info

curl -u {ambari-username}:{ambari-password} -H "X-Requested-By: ambari" -X GET http://{ambari-host}:{ambari-port}/api/v1/clusters/{clustername}/hosts/{host-name}/host_components?fields=HostRoles/state


Sample response:

{
  "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03/host_components?fields=HostRoles/state",
  "items": [
    {
      "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03/host_components/ACCUMULO_CLIENT",
      "HostRoles": {
        "cluster_name": "cl1",
        "component_name": "ACCUMULO_CLIENT",
        "host_name": "master03",
        "state": "INSTALLED"
      },
      "host": {
        "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03"
      }
    },
    {
      "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03/host_components/APP_TIMELINE_SERVER",
      "HostRoles": {
        "cluster_name": "cl1",
        "component_name": "APP_TIMELINE_SERVER",
        "host_name": "master03",
        "state": "STARTED"
      },
      "host": {
        "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03"
      }
    }
  ]
}

Thanks,

Aditya
