Types

type ClusterControllerCallOptions

type ClusterControllerCallOptions struct {
	CreateCluster   []gax.CallOption
	UpdateCluster   []gax.CallOption
	DeleteCluster   []gax.CallOption
	GetCluster      []gax.CallOption
	ListClusters    []gax.CallOption
	DiagnoseCluster []gax.CallOption
}

ClusterControllerCallOptions contains the retry settings for each method of ClusterControllerClient.

type ClusterControllerClient

type ClusterControllerClient struct {

	// LROClient is used internally to handle longrunning operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient

	// The call options for this service.
	CallOptions *ClusterControllerCallOptions
	// contains filtered or unexported fields
}

ClusterControllerClient is a client for interacting with Google Cloud Dataproc API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewClusterControllerClient

func NewClusterControllerClient(ctx context.Context, opts ...option.ClientOption) (*ClusterControllerClient, error)

NewClusterControllerClient creates a new cluster controller client.

The ClusterControllerService provides methods to manage clusters of Google Compute Engine instances.

Example
ctx := context.Background()
c, err := dataproc.NewClusterControllerClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c
Output:

func (*ClusterControllerClient) Close

func (c *ClusterControllerClient) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*ClusterControllerClient) Connection

func (c *ClusterControllerClient) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*ClusterControllerClient) CreateCluster

CreateCluster creates a cluster in a project.

}

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