Description:
 def get_cluster( self, project_id, region, cluster_name, retry=google.api_core.gapic_v1.method.DEFAULT, timeout=google.api_core.gapic_v1.method.DEFAULT, metadata=None, ):
 """ Gets the resource representation for a cluster in a project. Example: Args: project_id (str):
 Required. The ID of the Google Cloud Platform project that the cluster belongs to. region (str):
 Required. The Cloud Dataproc region in which to handle the request. cluster_name (str):
 Required. The cluster name. 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.Cluster` 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. """
