Package cloud.google.com/go/dataproc/apiv1 (v0.75.0)

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

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

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.

JobControllerClient

type JobControllerClient struct {

	// LROClient is used internally to handle longrunning operations.
	// It is exposed so that its CallOptions can be modified if required.

	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use client.

}

func (*JobControllerClient) CancelJob

CancelJob starts a job cancellation request. To access the job resource after cancellation, call regions/{region}/jobs.list (at https://cloud.google.com/dataproc/docs/reference/rest/v1/projects.regions.jobs/list) or regions/{region}/jobs.get (at https://cloud.google.com/dataproc/docs/reference/rest/v1/projects.regions.jobs/get).
