Apache Ambariとgroovyで、サービスを停止する

Apache Ambariとgroovyで、サービスを停止するには、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 org.apache.http.entity.*
import groovy.json.*

def host = "192.168.1.249" // replace this
def port = 8080
def user = "admin"
def password = "admin"
def cluster = "cluster1"
def service = "HIVE"

def httpclient = new DefaultHttpClient()
httpclient.withCloseable {
  def method = new HttpPut(
    "http://${user}:${password}@${host}:${port}/api/v1/clusters/${cluster}/services/${service}"
  )
  println method
  def json = new JsonBuilder()
  json (
    ["Body":[ServiceInfo:[ "state":"INSTALLED" ]]]
  )
  println json
  method.setHeader("content-Type", "application/x-www-form-urlencoded")
  method.setHeader("X-Requested-By", "ambari")
  method.setEntity(new StringEntity(json.toString(), "UTF-8"))
  def response = httpclient.execute(method)

  println response.getStatusLine().getStatusCode()

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

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