Class ClusterControllerClient (2.28.0)

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

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

CreateCluster(std::string const &, std::string const &, google::cloud::dataproc::v1::Cluster const &, Options)

Creates a cluster in a project.

The returned Operation.metadata will be ClusterOperationMetadata.

Parameters
Name Description
project_id std::string const &

Required. The ID of the Google Cloud Platform project that the cluster belongs to.

region std::string const &

Required. The Dataproc region in which to handle the request.

cluster google::cloud::dataproc::v1::Cluster const &

Returns
Type Description
future< StatusOr< google::cloud::dataproc::v1::Cluster > >

A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a google.cloud.dataproc.v1.Cluster proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

CreateCluster(NoAwaitTag, std::string const &, std::string const &, google::cloud::dataproc::v1::Cluster const &, Options)

Creates a cluster in a project.

Specifying the NoAwaitTag immediately returns the [google::longrunning::Operation] that corresponds to the Long Running Operation that has been started. No polling for operation status occurs.

ACTIVE contains the CREATING, UPDATING, and RUNNING states. INACTIVE contains the DELETING and ERROR states. clusterName is the name of the cluster provided at creation time. Only the logical AND operator is supported; space-separated items are treated as having an implicit AND operator.
Example filter:
