Example: >>> from google.cloud import dataproc_v1beta2 >>> >>> client = dataproc_v1beta2.ClusterControllerClient() >>> >>> # TODO: Initialize `project_id`: >>> project_id = '' >>> >>> # TODO: Initialize `region`: >>> region = '' >>> >>> # Iterate over all results >>> for element in client.list_clusters(project_id, region): ... # process element ... pass >>> >>> >>> # Alternatively: >>> >>> # Iterate over results one page at a time >>> for page in client.list_clusters(project_id, region).pages: ... for element in page: ... # process element ... pass 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. filter_ (str): 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 (int): 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. retry (Optional[google.api_core.retry.Retry]): A retry object used to retry requests. If ``None`` is specified, requests will be retried using a default configuration. 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.api_core.page_iterator.PageIterator` instance. An iterable of :class:`~google.cloud.dataproc_v1beta2.types.Cluster` instances. You can also iterate over the pages of the response using its `pages` property. 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.
