创建集群

gcloud

要在命令行中创建 Dataproc 集群，请运行 gcloud gclid clusters create 命令行中的命令 Cloud Shell。

gcloud dataproc clusters create CLUSTER_NAME \
    --region=REGION

该命令会利用适用于您主虚拟机实例和工作器虚拟机实例、磁盘大小和类型、网络类型、部署集群的区域和区域的默认 Dataproc 服务设置以及其他集群设置创建一个集群。要了解如何使用命令行标记自定义集群设置，请参阅 gcloud dataproc clusters create 命令。

使用 YAML 文件创建集群

1. 运行以下 gcloud 命令将现有 Dataproc 集群的配置导出到 cluster.yaml 文件中。

   gcloud dataproc clusters export EXISTING_CLUSTER_NAME \
       --region=REGION \
       --destination=cluster.yaml
   

2. 通过导入 YAML 文件配置来创建新集群。

   gcloud dataproc clusters import NEW_CLUSTER_NAME \
       --region=REGION \
       --source=cluster.yaml
   

注意：在执行导出操作的过程中，特定于集群的字段（例如集群名称）、仅限输出的字段和自动应用的标签会被过滤掉。在用于创建集群的导入的 YAML 文件中，不允许使用这些字段。

REST

本部分介绍如何创建采用所需值和默认配置（1 个主节点，2 个工作器节点）的集群。

在使用任何请求数据之前，请先进行以下替换：

• CLUSTER_NAME：集群名称
• PROJECT：Google Cloud 项目 ID
• REGION：可用的 Compute Engine 将在其中创建集群的区域。
• ZONE：集群将在所选区域内的可选可用区中创建。

HTTP 方法和网址：

POST https://dataproc.googleapis.com/v1/projects/PROJECT/regions/REGION/clusters

请求 JSON 正文：

{
  "project_id":"PROJECT",
  "cluster_name":"CLUSTER_NAME",
  "config":{
    "master_config":{
      "num_instances":1,
      "machine_type_uri":"n1-standard-2",
      "image_uri":""
    },
    "softwareConfig": {
      "imageVersion": "",
      "properties": {},

您应该收到类似以下内容的 JSON 响应：

    "description": "Create cluster with 2 workers",
    "warnings": [
      "For PD-Standard without local SSDs, we strongly recommend provisioning 1TB ...""
    ]
  }
}

控制台

在浏览器中打开 Google Cloud 控制台中的 Dataproc 创建集群页面，然后在在 Compute Engine 上创建 Dataproc 集群页面的Compute Engine 行中，点击“集群”中的创建。选择“设置集群”面板，其中的字段填充默认值。您可以选择每个面板，然后确认或更改默认值以自定义您的集群。

单击创建以创建集群。集群名称显示在集群页面中，预配集群后，其状态会更新为“正在运行”。点击集群名称以打开集群详情 页面，您可以检查应用的作业、实例和配置设置， 并连接到集群上运行的网页界面。
