   See [our internal issue](https://github.com/stackabletech/hdfs-operator/issues/626) and [the fix](https://github.com/kube-rs/kube/pull/2042) for details ([#840]).
 - Task logs are served from `BASE_LOG_FOLDER` instead of the `task` handler's `base_log_folder` at the Vector agent log directory ([#834]).
 - Avoid Python import race conditions by pre-cloning the git repo not only for Celery-based stacklets, but also for Kubernetes executor-based setups ([#844]).
+- The Airflow 3.x scheduler container now supervises the scheduler instead of the dag-processor. Before, a dead scheduler left the Pod `Running` and `Ready` with nothing scheduling DAGs ([#847]).

 * `executors`: the CeleryExecutor or KubernetesExecutor nodes over which the job workload is distributed by the scheduler
 * `scheduler`: responsible for triggering jobs and persisting their metadata to the backend database
 * `dagProcessors`: (Optional) responsible for monitoring, parsing and preparing DAGs for processing.

+If this role is not specified then the process will be started as a scheduler subprocess (Airflow 2.x), or as a standalone process in the same container as the scheduler (Airflow 3.x+). We recommend specifying this role for production settings as running multiple processes in the same container complicates proper supervision.
 * `triggerers`: (Optional) DAGs making use of deferrable operators can be used together with one or more triggerer processes to free up worker slots.
 This deferral process is also useful for providing a measure of high availability
