Documentation

Overview

Package dataproc is an auto-generated package for the Cloud Dataproc API.

Manages Hadoop-based clusters and jobs on Google Cloud Platform. 

NOTE: This package is in beta. It is not stable, and may be subject to changes.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

InstantiateInlineWorkflowTemplateOperation returns a new InstantiateInlineWorkflowTemplateOperation from a given name. The name must be that of a previously created InstantiateInlineWorkflowTemplateOperation, possibly from a different process.

func (*WorkflowTemplateClient) InstantiateWorkflowTemplate 

func (c *WorkflowTemplateClient) InstantiateWorkflowTemplate(ctx context.Context, req *dataprocpb.InstantiateWorkflowTemplateRequest, opts ...gax.CallOption) (*InstantiateWorkflowTemplateOperation, error)

InstantiateWorkflowTemplate instantiates a template and begins execution.

The returned Operation can be used to track execution of workflow by polling operations.get. The Operation will complete when entire workflow is finished.

The running workflow can be aborted via operations.cancel. This will cause any inflight jobs to be cancelled and workflow-owned clusters to be deleted.

The Operation.metadata will be WorkflowMetadata (at https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1beta2#workflowmetadata). Also see Using WorkflowMetadata (at https://cloud.google.com/dataproc/docs/concepts/workflows/debugging#using_workflowmetadata).

On successful completion, Operation.response will be Empty.

Example 
package main

import (
	"context"

	dataproc "cloud.google.com/go/dataproc/apiv1beta2"

	dataprocpb "google.golang.org/genproto/googleapis/cloud/dataproc/v1beta2"
)

func main() {
	// import dataprocpb "google.golang.org/genproto/googleapis/cloud/dataproc/v1beta2"

	ctx := context.Background()
	c, err := dataproc.NewWorkflowTemplateClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &dataprocpb.InstantiateWorkflowTemplateRequest{
		// TODO: Fill request struct fields.
	}
	op, err := c.InstantiateWorkflowTemplate(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}

	err = op.Wait(ctx)
	if err != nil {
		// TODO: Handle error.
	}
}

Output:

func (*WorkflowTemplateClient) InstantiateWorkflowTemplateOperation 

func (c *WorkflowTemplateClient) InstantiateWorkflowTemplateOperation(name string) *InstantiateWorkflowTemplateOperation

InstantiateWorkflowTemplateOperation returns a new InstantiateWorkflowTemplateOperation from a given name. The name must be that of a previously created InstantiateWorkflowTemplateOperation, possibly from a different process.

func (*WorkflowTemplateClient) ListWorkflowTemplates 

func (c *WorkflowTemplateClient) ListWorkflowTemplates(ctx context.Context, req *dataprocpb.ListWorkflowTemplatesRequest, opts ...gax.CallOption) *WorkflowTemplateIterator

ListWorkflowTemplates lists workflows that match the specified filter in the request.

Example 
package main

import (
	"context"

	dataproc "cloud.google.com/go/dataproc/apiv1beta2"
	"google.golang.org/api/iterator"

	dataprocpb "google.golang.org/genproto/googleapis/cloud/dataproc/v1beta2"
)

func main() {
	// import dataprocpb "google.golang.org/genproto/googleapis/cloud/dataproc/v1beta2"
	// import "google.golang.org/api/iterator"

	ctx := context.Background()
	c, err := dataproc.NewWorkflowTemplateClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &dataprocpb.ListWorkflowTemplatesRequest{
		// TODO: Fill request struct fields.
	}
	it := c.ListWorkflowTemplates(ctx, req)
	for {
		resp, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			// TODO: Handle error.
		}
		// TODO: Use resp.
		_ = resp
	}
}

Output:

func (*WorkflowTemplateClient) UpdateWorkflowTemplate 

func (c *WorkflowTemplateClient) UpdateWorkflowTemplate(ctx context.Context, req *dataprocpb.UpdateWorkflowTemplateRequest, opts ...gax.CallOption) (*dataprocpb.WorkflowTemplate, error)

UpdateWorkflowTemplate updates (replaces) workflow template. The updated template must contain version that matches the current server version.

Example 
package main

import (
	"context"

	dataproc "cloud.google.com/go/dataproc/apiv1beta2"

	dataprocpb "google.golang.org/genproto/googleapis/cloud/dataproc/v1beta2"
)

func main() {
	// import dataprocpb "google.golang.org/genproto/googleapis/cloud/dataproc/v1beta2"

	ctx := context.Background()
	c, err := dataproc.NewWorkflowTemplateClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}

	req := &dataprocpb.UpdateWorkflowTemplateRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.UpdateWorkflowTemplate(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

type WorkflowTemplateIterator 

type WorkflowTemplateIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.
	//
	// InternalFetch returns results from a single call to the underlying RPC.
	// The number of results is no greater than pageSize.
	// If there are no more results, nextPageToken is empty and err is nil.
	InternalFetch func(pageSize int, pageToken string) (results []*dataprocpb.WorkflowTemplate, nextPageToken string, err error)
	// contains filtered or unexported fields
}

WorkflowTemplateIterator manages a stream of *dataprocpb.WorkflowTemplate.

func (*WorkflowTemplateIterator) Next 

func (it *WorkflowTemplateIterator) Next() (*dataprocpb.WorkflowTemplate, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*WorkflowTemplateIterator) PageInfo 

func (it *WorkflowTemplateIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.
