Description

Description

Right now, when the tasks fail due to pod launch failures or the pod is stuck in the pending phase, then the task logs from the UI are empty. It is very inconvenient for airflow consumers to debug it. They might not have access to the scheduler logs. I believe we can push these failure reasons from the Kubernetes executor to task attempt logs (remote). So, that airflow consumers can able to see task failure reasons from the UI.

Use case/motivation

Right now, when the tasks fail due to pod launch failures or the pod is stuck in the pending phase, then the task logs from the UI are empty. It is very inconvenient for airflow consumers to debug it.
