> KubernetesExecutor hangs on task queueing
> -----------------------------------------
>
> Key: AIRFLOW-5447

> Starting in 1.10.4, and continuing in 1.10.5, when using the
> KubernetesExecutor, with the webserver and scheduler running in the
> kubernetes cluster, tasks are scheduled, but when added to the task queue,
> the executor process hangs indefinitely. Based on log messages, it appears to
> be stuck at this line
