Google Cloud Dataproc V1 Client - Class ClusterControllerClient (3.6.1)

Reference documentation and code samples for the Google Cloud Dataproc V1 Client class ClusterControllerClient.

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

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$clusterControllerClient = new ClusterControllerClient();
try {
    $projectId = 'project_id';
    $region = 'region';
    $cluster = new Cluster();
    $operationResponse = $clusterControllerClient->createCluster($projectId, $region, $cluster);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $clusterControllerClient->createCluster($projectId, $region, $cluster);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $clusterControllerClient->resumeOperation($operationName, 'createCluster');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $clusterControllerClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Methods

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

cluster: projects/{project}/locations/{location}/clusters/{cluster}
clusterRegion: projects/{project}/regions/{region}/clusters/{cluster}
nodeGroup: projects/{project}/regions/{region}/clusters/{cluster}/nodeGroups/{node_group}

`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport.

updateCluster

Updates a cluster in a project. The returned Operation.metadata will be ClusterOperationMetadata.

The cluster must be in a RUNNING state or an error is returned.

Parameters

Name Description

projectId

string

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

region

string

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

clusterName

string

Required. The cluster name.

cluster

Google\Cloud\Dataproc\V1\Cluster

Required. The changes to the cluster.

updateMask

Google\Protobuf\FieldMask

Required. Specifies the path, relative to Cluster, of the field to update. For example, to change the number of workers in a cluster to 5, the update_mask parameter would be specified as config.worker_config.num_instances, and the PATCH request body would specify the new value, as follows:

{ "config":{ "workerConfig":{ "numInstances":"5" } } } Similarly, to change the number of preemptible workers in a cluster to 5, the update_mask parameter would be config.secondary_worker_config.num_instances, and the PATCH request body would be set as follows:

{ "config":{ "secondaryWorkerConfig":{ "numInstances":"5" } } } Note: Currently, only the following fields can be updated:

Mask	Purpose
*labels*	Update labels
*config.worker_config.num_instances*	Resize primary worker group
*config.secondary_worker_config.num_instances*	Resize secondary worker group
config.autoscaling_config.policy_uri	Use, stop using, or change autoscaling policies

optionalArgs

array

Optional.

↳ gracefulDecommissionTimeout

Duration

Optional. Timeout for graceful YARN decommissioning. Graceful decommissioning allows removing nodes from the cluster without interrupting jobs in progress. 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.

↳ requestId

string

Optional. A unique ID used to identify the request. If the server receives two UpdateClusterRequests with the same id, then the second request will be ignored and the first google.longrunning.Operation created and stored in the backend is returned. It is recommended to always 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.

↳ retrySettings

RetrySettings|array

Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.
