JobControllerClient

JobControllerClient

The JobController provides methods to manage jobs.

Constructor

new JobControllerClient(optionsopt, gaxInstanceopt)

Construct an instance of JobControllerClient.

Parameters:
Name Type Attributes Description
options object <optional>

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties
Name Type Attributes Description
credentials object <optional>

Credentials object.

Properties
Name Type Attributes Description
client_email string <optional>
private_key string <optional>
email string <optional>

Account email address. Required when using a .pem or .p12 keyFilename.
keyFilename string <optional>

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.
port number <optional>

The port on which to connect to the remote host.
projectId string <optional>

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.
apiEndpoint string <optional>

The domain name of the API remote host.
clientConfig gax.ClientConfig <optional>

Client configuration override. Follows the structure of gapicConfig.
fallback boolean | "rest" <optional>

Use HTTP fallback mode. Pass "rest" to use HTTP/1.1 REST API instead of gRPC. For more information, please check the documentation.
gaxInstance gax <optional>

loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new JobControllerClient({fallback: 'rest'}, gax);

Members

apiEndpoint

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

port

The port for this API service.

scopes

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

The DNS address for this API service.

Methods

batchPath(project, location, batch) → {string}

Return a fully-qualified batch resource name string.

Parameters:
Name Type Description
project string
location string
batch string
Returns:
Type Description
string

Resource name string.

(async) checkSubmitJobAsOperationProgress(name) → {Promise}

Check the status of the long running operation returned by submitJobAsOperation().

Parameters:
Name Type Description
name String

The operation name that will be passed.
Returns:
Type Description
Promise
  • The promise which resolves to an object. The decoded operation object has result and metadata field to get information from. Please see the documentation for more details and examples.
Example
  /**
   * This snippet has been automatically generated and should be regarded as a code template only.
   * It will require modifications to work.
   * It may require correct/in-range values for request initialization.
   * TODO(developer): Uncomment these variables before running the sample.
   */
  /**
   *  Required. The ID of the Google Cloud Platform project that the job
   *  belongs to.
   */
  // const projectId = 'abc123'
  /**
   *  Required. The Dataproc region in which to handle the request.
   */
  // const region = 'us-central1'
  /**
   *  Required. The job resource.
   */
  // const job = {}
  /**
   *  Optional. A unique id used to identify the request. If the server
   *  receives two
   *  SubmitJobRequest (https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#google.cloud.dataproc.v1.SubmitJobRequest)s
   *  with the same id, then the second request will be ignored and the
   *  first Job google.cloud.dataproc.v1.Job  created and stored in the backend
   *  is returned.
   *  It is recommended to always set this value to a
   *  UUID (https://en.wikipedia.org/wiki/Universally_unique_identifier).
   *  The id must contain only letters (a-z, A-Z), numbers (0-9),
   *  underscores (_), and hyphens (-). The maximum length is 40 characters.
   */
  // const requestId = 'abc123'

  // Imports the Dataproc library
  const {JobControllerClient} = require('@google-cloud/dataproc').v1;

  // Instantiates a client
  const dataprocClient = new JobControllerClient();

  async function callSubmitJobAsOperation() {
    // Construct request
    const request = {
      projectId,
      region,
      job,
    };

    // Run request
    const [operation] = await dataprocClient.submitJobAsOperation(request);
    const [response] = await operation.promise();
    console.log(response);
  }

  callSubmitJobAsOperation();

close() → {Promise}

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns:
Type Description
Promise

A promise that resolves when the client is closed.

getProjectId() → {Promise}

Return the project ID used by this class.

Returns:
Type Description
Promise

A promise that resolves to string containing the project ID.

initialize() → {Promise}

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns:
Type Description
Promise

A promise that resolves to an authenticated service stub.

listJobsAsync(request, optionsopt) → {Object}

Equivalent to listJobs, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
projectId string

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

Required. The Dataproc region in which to handle the request.
pageSize number <optional>

Optional. The number of results to return in each response.
pageToken string <optional>

Optional. The page token, returned by a previous call, to request the next page of results.
clusterName string <optional>

Optional. If set, the returned jobs list includes only jobs that were submitted to the named cluster.
jobStateMatcher google.cloud.dataproc.v1.ListJobsRequest.JobStateMatcher <optional>

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

If filter is provided, jobStateMatcher will be ignored.
filter string <optional>

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 object <optional>

Call options. See CallOptions for more details.
Returns:
Type Description
Object

An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing Job. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.
Example
  /**
   * This snippet has been automatically generated and should be regarded as a code template only.
   * It will require modifications to work.
