On Airflow instances with the Kubernetes executor, a task will immediately fail if its worker pod is deleted/ evicted in the pending state. A new worker pod is not spun up to replace it, and the task fails with the below error message.
This failure is triggered by this line in the source code.
If the task is not failed upon worker pod deletion, it will remain in the queued state until it reaches
task_queued_timeout. Once this timeout is reached, internal retries will be allowed due to PR #43520 and a new worker pod will be spun up for the task. Therefore, if the first worker pod was deleted or evicted due to a temporary issue, the task will be able to run on the newly spun up worker pod.In this PR, I have removed the code that fails the task when its pending worker pod is deleted. This will prevent task failures from temporary issues with pending worker pods.
