Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the NodeGroupController 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 configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#create_node_group(request, options = nil) ⇒ ::Gapic::Operation #create_node_group(parent: nil, node_group: nil, node_group_id: nil, request_id: nil) ⇒ ::Gapic::Operation

Creates a node group in a cluster. The returned Operation.metadata is NodeGroupOperationMetadata.

Examples:

Basic example

require "google/cloud/dataproc/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Dataproc::V1::NodeGroupController::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Dataproc::V1::CreateNodeGroupRequest.new

# Call the create_node_group method.
result = client.create_node_group request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #create_node_group(request, options = nil) ⇒ ::Gapic::Operation

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

    Parameters:

    • request (::Google::Cloud::Dataproc::V1::CreateNodeGroupRequest, ::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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #create_node_group(parent: nil, node_group: nil, node_group_id: nil, request_id: nil) ⇒ ::Gapic::Operation

    Pass arguments to create_node_group 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:

    • parent (::String) (defaults to: nil) —

      Required. The parent resource where this node group will be created. Format: projects/{project}/regions/{region}/clusters/{cluster}

    • node_group (::Google::Cloud::Dataproc::V1::NodeGroup, ::Hash) (defaults to: nil) —

      Required. The node group to create.

    • node_group_id (::String) (defaults to: nil) —

      Optional. An optional node group ID. Generated if not specified.

      The ID must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). Cannot begin or end with underscore or hyphen. Must consist of from 3 to 33 characters.

    • request_id (::String) (defaults to: nil) —

      Optional. A unique ID used to identify the request. If the server receives two CreateNodeGroupRequest with the same ID, the second request is ignored and the first google.longrunning.Operation created and stored in the backend is returned.

      Recommendation: 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.

#resize_node_group(request, options = nil) ⇒ ::Gapic::Operation #resize_node_group(name: nil, size: nil, request_id: nil, graceful_decommission_timeout: nil) ⇒ ::Gapic::Operation

Resizes a node group in a cluster. The returned Operation.metadata is NodeGroupOperationMetadata.

Examples:

Basic example

require "google/cloud/dataproc/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Dataproc::V1::NodeGroupController::Client.new

# Create a request. To set request fields, pass in keyword arguments.

# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #resize_node_group(request, options = nil) ⇒ ::Gapic::Operation

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

    Parameters:

    • request (::Google::Cloud::Dataproc::V1::ResizeNodeGroupRequest, ::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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #resize_node_group(name: nil, size: nil, request_id: nil, graceful_decommission_timeout: nil) ⇒ ::Gapic::Operation

    Pass arguments to resize_node_group 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:

    • name (::String) (defaults to: nil) —

      Required. The name of the node group to resize. Format: projects/{project}/regions/{region}/clusters/{cluster}/nodeGroups/{nodeGroup}

    • size (::Integer) (defaults to: nil) —

      Required. The number of running instances for the node group to maintain. The group adds or removes instances to maintain the number of instances specified by this parameter.

    • request_id (::String) (defaults to: nil) —

      Optional. A unique ID used to identify the request. If the server receives two ResizeNodeGroupRequest with the same ID, the second request is ignored and the first google.longrunning.Operation created and stored in the backend is returned.

      Recommendation: 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.

    • graceful_decommission_timeout (::Google::Protobuf::Duration, ::Hash) (defaults to: nil) —

      Optional. Timeout for graceful YARN decommissioning. Graceful decommissioning allows the removal of nodes from the Compute Engine node group without interrupting jobs in progress. This 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.

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.
