Description

STR:

1. Install ZooKeeper
2. Try to add Metrics Collector and Metrics Monitor using Add Service request

{
  "operation_type": "ADD_SERVICE",
  "components": [
    { "name": "METRICS_COLLECTOR", "hosts": [ { "fqdn": "c7401.ambari.apache.org" } ] },
    { "name": "METRICS_MONITOR", "hosts": [ { "fqdn": "c7401.ambari.apache.org" } ] }
  ]
}

Result: Metrics Grafana is also installed. It is being added by the layout recommendation, which should not be invoked if full layout is explicitly specified in the request (ie. no "services" part is present).
