Constructor Details

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

Returns a new instance of JobControllerClient.

Parameters:

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

    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>) (defaults to: ALL_SCOPES) —

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

  • client_config (Hash) (defaults to: {}) —

    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) (defaults to: DEFAULT_TIMEOUT) —

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

  • metadata (Hash) (defaults to: nil) —

    Default metadata to be sent with each request. This can be overridden on a per call basis.

  • exception_transformer (Proc) (defaults to: nil) —

    An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.

# TODO: Initialize `project_id`:
project_id = ''

# TODO: Initialize `region`:
region = ''

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

# Or iterate over results one page at a time.
job_controller_client.list_jobs(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 job belongs to.

  • region (String) —

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

  • page_size (Integer) (defaults to: nil) —

    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.

  • cluster_name (String) (defaults to: nil) —

    Optional. If set, the returned jobs list includes only jobs that were submitted to the named cluster.

  • job_state_matcher (Google::Cloud::Dataproc::V1::ListJobsRequest::JobStateMatcher) (defaults to: nil) —

    Optional. Specifies enumerated categories of jobs to list. (default = match ALL jobs).

    If filter is provided, jobStateMatcher will be ignored.

  • filter (String) (defaults to: nil) —

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

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

    where field is status.state or labels.[KEY], and [KEY] is a label key. value can be * to match all values. status.state can be either ACTIVE or NON_ACTIVE. Only the logical AND operator is supported; space-separated items are treated as having an implicit AND operator.

    Example filter:

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

  • options (Google::Gax::CallOptions) (defaults to: nil) —

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

Yields:

  • (result, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

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

    An enumerable of Google::Cloud::Dataproc::V1::Job 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.

#submit_job(project_id, region, job, request_id: nil, options: nil) {|result, operation| ... } ⇒ Google::Cloud::Dataproc::V1::Job

Submits a job to a cluster.

Examples:

require "google/cloud/dataproc"

job_controller_client = Google::Cloud::Dataproc::JobController.new(version: :v1)

# TODO: Initialize `project_id`:
project_id = ''

# TODO: Initialize `region`:
region = ''

job = {}
response = job_controller_client.submit_job(project_id, region, job)

Parameters:

  • project_id (String) —

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

  • region (String) —

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

  • request_id (String) (defaults to: nil) —

    Optional. A unique id used to identify the request. If the server receives two SubmitJobRequest requests with the same id, then the second request will be ignored and the first Job 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.

  • options (Google::Gax::CallOptions) (defaults to: nil) —

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

Yields:

  • (result, operation) —

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

    Required. Specifies the path, relative to Job, of the field to update. For example, to update the labels of a Job the update_mask parameter would be specified as labels, and the PATCH request body would specify the new value. Note: Currently, labels is the only field that can be updated. A hash of the same form as Google::Protobuf::FieldMask can also be provided.

  • options (Google::Gax::CallOptions) (defaults to: nil) —
