                in a cluster to 5, the ``update_mask`` parameter would
                be ``config.secondary_worker_config.num_instances``, and

                label key. **value** can be ``*`` to match all values.

                ``ACTIVE``, ``INACTIVE``, ``CREATING``, ``RUNNING``,
                ``ERROR``, ``DELETING``, or ``UPDATING``. ``ACTIVE``

                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:

                labels.env = staging AND labels.starred = \*

            retry (google.api_core.retry.Retry): Designation of what errors, if any,

                The request object. A request to collect cluster
                diagnostic information.
            project_id (:class:`str`):

                Platform project that the cluster
                belongs to.

                This corresponds to the ``project_id`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            region (:class:`str`):
                Required. The Dataproc region in
                which to handle the request.

                This corresponds to the ``region`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            cluster_name (:class:`str`):
                Required. The cluster name.
                This corresponds to the ``cluster_name`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry.Retry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.api_core.operation_async.AsyncOperation:
                An object representing a long-running operation.

                The result type for the operation will be
