Methods

ClusterControllerClient

ClusterControllerClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.dataproc_v1.services.cluster_controller.transports.base.ClusterControllerTransport] = None, client_options: <module 'google.api_core.client_options' from '/workspace/python-dataproc/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None)

Instantiate the cluster controller client.

Parameters
Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, .ClusterControllerTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint, this is the default value for the environment variable) and "auto" (auto switch to the default mTLS endpoint if client SSL credentials is present). However, the `api_endpoint` property takes precedence if provided. (2) The `client_cert_source` property is used to provide client SSL credentials for mutual TLS transport. If not provided, the default SSL credentials will be used if present.

Exceptions
Type	Description
`google.auth.exceptions.MutualTLSChannelError`	If mutual TLS transport creation failed for any reason.
