Constructor Details

#initialize(credentials: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, lib_name: nil, lib_version: "") ⇒ ClusterControllerClient

Returns a new instance of ClusterControllerClient

Parameters:

  • credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) —

    Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

  • scopes (Array<String>) —

    The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

  • client_config (Hash) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) —

    The default timeout, in seconds, for calls made through this client.

require "google/cloud/dataproc/v1"

cluster_controller_client = Google::Cloud::Dataproc::V1::ClusterController.new
project_id = ''
region = ''
cluster_name = ''

# Register a callback during the method call.
operation = cluster_controller_client.diagnose_cluster(project_id, region, cluster_name) do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Or use the return value to register a callback.
operation.on_done do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Manually reload the operation.
operation.reload!

# Or block until the operation completes, triggering callbacks on
# completion.
operation.wait_until_done!

#list_clusters(project_id, region, filter: nil, page_size: nil, options: nil) ⇒ Google::Gax::PagedEnumerable<Google::Cloud::Dataproc::V1::Cluster>

Lists all regions/region/clusters in a project.

Examples:

require "google/cloud/dataproc/v1"

cluster_controller_client = Google::Cloud::Dataproc::V1::ClusterController.new
project_id = ''
region = ''

# Iterate over all results.
cluster_controller_client.list_clusters(project_id, region).each do |element|
  # Process element.
end

# Or iterate over results one page at a time.
cluster_controller_client.list_clusters(project_id, region).each_page do |page|
  # Process each page at a time.
  page.each do |element|
    # Process element.
  end
end

Parameters:

  • project_id (String) —

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

  • region (String) —

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

  • filter (String) —

    Optional. A filter constraining the clusters to list. Filters are case-sensitive and have the following syntax:

    field = value [AND [field = value]] ...

    where field is one of +status.state+, +clusterName+, or +labels.[KEY]+, and +[KEY]+ is a label key. value can be +*+ to match all values. +status.state+ can be one of the following: +ACTIVE+, +INACTIVE+, +CREATING+, +RUNNING+, +ERROR+, +DELETING+, or +UPDATING+. +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:

    status.state = ACTIVE AND clusterName = mycluster AND labels.env = staging AND labels.starred = *

  • page_size (Integer) —

    The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Returns:

  • (Google::Gax::PagedEnumerable<Google::Cloud::Dataproc::V1::Cluster>) —

    An enumerable of Google::Cloud::Dataproc::V1::Cluster instances. See Google::Gax::PagedEnumerable documentation for other operations such as per-page iteration or access to the response object.

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.

#update_cluster(project_id, region, cluster_name, cluster, update_mask, options: nil) ⇒ Google::Gax::Operation

Updates a cluster in a project.

Examples:

require "google/cloud/dataproc/v1"

cluster_controller_client = Google::Cloud::Dataproc::V1::ClusterController.new
project_id = ''
region = ''
cluster_name = ''
cluster = {}
update_mask = {}

# Register a callback during the method call.
operation = cluster_controller_client.update_cluster(project_id, region, cluster_name, cluster, update_mask) do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Or use the return value to register a callback.
operation.on_done do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Manually reload the operation.
operation.reload!

# Or block until the operation completes, triggering callbacks on
# completion.
operation.wait_until_done!

Parameters:

  • project_id (String) —

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

  • region (String) —

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

  • cluster_name (String) —

    Required. The cluster name.

  • cluster (Google::Cloud::Dataproc::V1::Cluster | Hash) —

    Required. The changes to the cluster. A hash of the same form as Google::Cloud::Dataproc::V1::Cluster can also be provided.

  • update_mask (Google::Protobuf::FieldMask | Hash) —

    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
    A hash of the same form as Google::Protobuf::FieldMask can also be provided.

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Returns:

  • (Google::Gax::Operation)

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
