Create a cluster

gcloud

To create a Dataproc cluster on the command line, run the gcloud dataproc clusters create command locally in a terminal window or in Cloud Shell.

gcloud dataproc clusters create CLUSTER_NAME \
    --region=REGION

The command creates a cluster with default Dataproc service settings for your master and worker virtual machine instances, disk sizes and types, network type, region and zone where your cluster is deployed, and other cluster settings. See the gcloud dataproc clusters create command for information on using command line flags to customize cluster settings.

Create a cluster with a YAML file

1. Run the following gcloud command to export the configuration of an existing Dataproc cluster into a cluster.yaml file.

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

2. Create a new cluster by importing the YAML file configuration.

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

Note: During the export operation, cluster-specific fields, such as cluster name, output-only fields, and automatically applied labels are filtered. These fields are disallowed in the imported YAML file used to create a cluster.

REST

This section shows how to create a cluster with required values and the default configuration (1 master, 2 workers).

Before using any of the request data, make the following replacements:

• CLUSTER_NAME: cluster name
• PROJECT: Google Cloud project ID
• REGION: An available Compute Engine region where the cluster will be created.
• ZONE: An optional zone within the selected region where the cluster will be created.

HTTP method and URL:

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

Request JSON body:

{
  "project_id":"PROJECT",
  "cluster_name":"CLUSTER_NAME",
  "config":{
    "master_config":{
      "num_instances":1,
      "machine_type_uri":"n1-standard-2",
      "image_uri":""
    },
    "softwareConfig": {
      "imageVersion": "",
      "properties": {},
      "optionalComponents": []
    },
    "worker_config":{
      "num_instances":2,
      "machine_type_uri":"n1-standard-2",
      "image_uri":""
    },
    "gce_cluster_config":{
      "zone_uri":"ZONE"
    }
  }
}

To send your request, expand one of these options:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://dataproc.googleapis.com/v1/projects/PROJECT/regions/REGION/clusters"

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

    -Uri "https://dataproc.googleapis.com/v1/projects/PROJECT/regions/REGION/clusters" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
"name": "projects/PROJECT/regions/REGION/operations/b5706e31......",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.dataproc.v1.ClusterOperationMetadata",

      "stateStartTime": "2019-11-21T00:37:56.220Z"
    },
    "operationType": "CREATE",
    "description": "Create cluster with 2 workers",
    "warnings": [
      "For PD-Standard without local SSDs, we strongly recommend provisioning 1TB ...""
    ]
  }
}

Console

Open the Dataproc Create a cluster page in the Google Cloud console in your browser, then click Create in the cluster on Compute engine row in the Create a Dataproc cluster on Compute Engine page. The Set up cluster panel is selected with fields filled in with default values. You can select each panel and confirm or change default values to customize your cluster.

Click Create to create the cluster. The cluster name appears in the Clusters page, and its status is updated to Running after the cluster is provisioned. Click the cluster name to open the cluster details page where you can examine jobs, instances, and configuration settings for your cluster and connect to web interfaces running on your cluster.
