Ambari Rest API 管理集群_ambari api

有时候因为网络端口活着其他限制原因，我们没办法直接访问ambari web ui的页面进行操作，这时候我们可以在能访问ambari server的linux服务器上执行curl命令来管理ambari集群
参考链接: https://github.com/apache/ambari/blob/trunk/ambari-server/docs/api/v1/index.md#resources.

1. 获取集群名称

curl -u username:password -H "X-Requested-By: ambari" -X GET http://ip.ip.ip.ip:8080/api/v1/clusters
{
  "href" : "http://localhost:8080/api/v1/clusters",
  "items" : [
    {
      "href" : "http://localhost:8080/api/v1/clusters/c1",
      "Clusters" : {
        "cluster_name" : "c1"
      }
    }
  ]
}

2. 获取集群的所有服务

curl -u username:password -H "X-Requested-By: ambari" -X GET http://ip.ip.ip.ip:8080/api/v1/clusters/c1/services
{
  "href" : "http://ip.ip.ip.ip:8080/api/v1/clusters/c1/services",
  "items" : [
  	......
    {
      "href" : "http://ip.ip.ip.ip:8080/api/v1/clusters/c1/services/HBASE",
      "ServiceInfo" : {
        "cluster_name" : "c1",
        "service_name" : "HBASE"
      }
    },
    {
      "href" : "http://ip.ip.ip.ip:8080/api/v1/clusters/c1/services/HDFS",
      "ServiceInfo" : {
        "cluster_name" : "c1",
        "service_name" : "HDFS"
      }
    },

    "items" : [
      {
        "href" : "http://ip.ip.ip.ip:8080/api/v1/clusters/c1/hosts/node-01",
        "Hosts" : {
          "cluster_name" : "c1",
          "host_name" : "node-01"
