Apache Ambariとgroovyで、サービスを開始する

Apache Ambariとgroovyで、サービスを開始するには、以下のようなコードを実行します。

サンプルコード

@Grab(group='org.apache.httpcomponents', module='httpclient', version='4.3.5')
import org.apache.http.client.methods.*
import org.apache.http.impl.client.*
import org.apache.http.message.*
import org.apache.http.auth.*
import groovy.json.*

def host = "192.168.1.240" // replace this
def port = 7180
def user = "admin"
def password = "admin"
def clusterName = "cluster"
def serviceName = "hive"

def httpclient = new DefaultHttpClient()
httpclient.withCloseable {
  httpclient.getCredentialsProvider().setCredentials(
    new AuthScope(host, port),
    new UsernamePasswordCredentials(user, password)
  )

  def cluster = "/api/v7/clusters/${clusterName}"
  def method = new HttpPost(
    "http://${host}:${port}${cluster}/services/${serviceName}/commands/start"
  )
  def response = httpclient.execute(method)
  println response.getStatusLine().getStatusCode()

  def json = new JsonSlurper().parseText(response.getEntity().getContent().text)
  println json
}

動作環境
Apache Ambari 1.6.1, HDP2.1, groovy 2.3.2
