 def submit_job( self, project_id, region, job, request_id=None, retry=google.api_core.gapic_v1.method.DEFAULT, timeout=google.api_core.gapic_v1.method.DEFAULT, metadata=None, ):
 """ Submits a job to a cluster. Example: Args: project_id (str):
 Required. The ID of the Google Cloud Platform project that the job belongs to. region (str):
 Required. The Cloud Dataproc region in which to handle the request. job (Union[dict, ~google.cloud.dataproc_v1beta2.types.Job]):
 Required. The job resource. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.dataproc_v1beta2.types.Job` request_id (str):
 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 <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. retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Returns: A :class:`~google.cloud.dataproc_v1beta2.types.Job` instance. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
