Dataproc resolves them into a ranked +list of widely available machine families to minimize stockouts. HO clusters +are always auto-zoned. + +The DAG creates an HO cluster, scales its primary workers through the +authoritative ``config.worker_flexible_config.num_instances`` update path, +scales the secondary workers through the legacy +``config.secondary_worker_config.num_instances`` compatibility path (which the +API keeps accepting for HO clusters), submits a Spark job and deletes the +cluster. +""" + +from __future__ import annotations + +import os +from datetime import datetime + +from airflow.models.dag import DAG +from airflow.providers.google.cloud.operators.dataproc import ( + ClusterGenerator, Review Comment: `ClusterGenerator ` is deprecated.
