Includes

Google::Cloud::Dataproc::V1::ClusterController::Paths

Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the ClusterController Client class.

See Configuration for a description of the configuration fields.

Yields

(config) — Configure the Client client.

Yield Parameter

config (Client::Configuration)

Returns

(Client::Configuration)

Example

# Modify the configuration for all ClusterController clients
::Google::Cloud::Dataproc::V1::ClusterController::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the ClusterController Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

See Configuration for a description of the configuration fields.

Yields

(config) — Configure the Client client.

Yield Parameter

config (Client::Configuration)

Returns

(Client::Configuration)

#create_cluster

def create_cluster(request, options = nil) -> ::Gapic::Operation
def create_cluster(project_id: nil, region: nil, cluster: nil, request_id: nil, action_on_failed_primary_workers: nil) -> ::Gapic::Operation

Creates a cluster in a project. The returned Operation.metadata will be ClusterOperationMetadata.

Overloads

def create_cluster(request, options = nil) -> ::Gapic::Operation

Pass arguments to create_cluster via a request object, either of type Google::Cloud::Dataproc::V1::CreateClusterRequest or an equivalent Hash.

Parameters

request (::Google::Cloud::Dataproc::V1::CreateClusterRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

def create_cluster(project_id: nil, region: nil, cluster: nil, request_id: nil, action_on_failed_primary_workers: nil) -> ::Gapic::Operation

Pass arguments to create_cluster via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

Parameters

project_id (::String) — Required. The ID of the Google Cloud Platform project that the cluster belongs to.
region (::String) — Required. The Dataproc region in which to handle the request.
cluster (::Google::Cloud::Dataproc::V1::Cluster, ::Hash) — Required. The cluster to create.
request_id (::String) — Optional. A unique ID used to identify the request. If the server receives two CreateClusterRequests with the same id, then the second request will be ignored and the first google.longrunning.Operation created and stored in the backend is returned.

It is recommended to always set this value to a UUID.

The ID must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters.
action_on_failed_primary_workers (::Google::Cloud::Dataproc::V1::FailureAction) — Optional. Failure action when primary worker creation fails.

Yields

(response, operation) — Access the result along with the RPC operation

Yield Parameters

response (::Gapic::Operation)

Raises

(::Google::Cloud::Error) — if the RPC is aborted.

Overloads

def update_cluster(request, options = nil) -> ::Gapic::Operation

Pass arguments to update_cluster via a request object, either of type UpdateClusterRequest or an equivalent Hash.

Parameters

request (::Google::Cloud::Dataproc::V1::UpdateClusterRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

def update_cluster(project_id: nil, region: nil, cluster_name: nil, cluster: nil, graceful_decommission_timeout: nil, update_mask: nil, request_id: nil) -> ::Gapic::Operation

Pass arguments to update_cluster via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

Parameters

project_id (::String) — Required. The ID of the Google Cloud Platform project the cluster belongs to.
region (::String) — Required. The Dataproc region in which to handle the request.
cluster_name (::String) — Required. The cluster name.
cluster (::Google::Cloud::Dataproc::V1::Cluster, ::Hash) — Required. The changes to the cluster.
graceful_decommission_timeout (::Google::Protobuf::Duration, ::Hash) — Optional. Timeout for graceful YARN decomissioning. Graceful decommissioning allows removing nodes from the cluster without interrupting jobs in progress. Timeout specifies how long to wait for jobs in progress to finish before forcefully removing nodes (and potentially interrupting jobs). Default timeout is 0 (for forceful decommission), and the maximum allowed timeout is 1 day. (see JSON representation of Duration).

Only supported on Dataproc image versions 1.2 and higher.

update_mask (::Google::Protobuf::FieldMask, ::Hash) — Required. Specifies the path, relative to Cluster, of the field to update. For example, to change the number of workers in a cluster to 5, the update_mask parameter would be specified as config.worker_config.num_instances, and the PATCH request body would specify the new value, as follows:

{
  "config":{
    "workerConfig":{
      "numInstances":"5"
    }
  }
}

Similarly, to change the number of preemptible workers in a cluster to 5, the update_mask parameter would be config.secondary_worker_config.num_instances, and the PATCH request body would be set as follows:

{
  "config":{
    "secondaryWorkerConfig":{
      "numInstances":"5"
    }
  }
}

Note: Currently, only the following fields can be updated:

Mask	Purpose
*labels*	Update labels
*config.worker_config.num_instances*	Resize primary worker group
*config.secondary_worker_config.num_instances*	Resize secondary worker group
config.autoscaling_config.policy_uri	Use, stop using, or change autoscaling policies

request_id (::String) — Optional. A unique ID used to identify the request. If the server receives two UpdateClusterRequests with the same id, then the second request will be ignored and the first google.longrunning.Operation created and stored in the backend is returned.

It is recommended to always set this value to a UUID.

The ID must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters.

Yields

(response, operation) — Access the result along with the RPC operation

Yield Parameters

response (::Gapic::Operation)
operation (::GRPC::ActiveCall::Operation)

Returns

(::Gapic::Operation)

Raises

(::Google::Cloud::Error) — if the RPC is aborted.
