Timeout for graceful YARN decommissioning. Graceful decommissioning allows removing nodes from the cluster without interrupting jobs in progress. Timeout specifies how long to wait for jobs in progress to finish before forcefully removing nodes (and potentially interrupting jobs). Default timeout is 0 (for forceful decommission), and the maximum allowed timeout is one day.

Only supported on Dataproc image versions 1.2 and higher.

If a dict is provided, it must be of the same form as the protobuf message Duration.
request_id (str | None) – A unique id used to identify the request. If the server receives two UpdateClusterRequest requests with the same ID, the second request will be ignored, and an operation created for the first one and stored in the backend is returned.
retry (google.api_core.retry.Retry | google.api_core.gapic_v1.method._MethodDefault) – A retry object used to retry requests. If None, requests will not be retried.
timeout (float | None) – The amount of time, in seconds, to wait for the request to complete. If retry is specified, the timeout applies to each individual attempt.
metadata (Sequence[tuple[str, str]]) – Additional metadata that is provided to the method.

async create_workflow_template(template, project_id, region, retry=DEFAULT, timeout=None, metadata=())[source]¶
