syedahsn opened a new pull request, #36179:
URL: https://github.com/apache/airflow/pull/36179
Currently, credentials are loaded once at the initialization of the ECS
Executor, and those credentials are used to authenticate to the ECS API. If
those credentials expire, the Executor will not able to schedule new tasks, or
update existing ones. There is no way to reload the credentials except by
restarting the scheduler.
The purpose of this PR is to allow the Executor to refresh its credentials
if they expire. It includes an exponential backoff retry method that retries
the credentials based on the previous attempt so that the API has a chance to
work through any transient issues, and to not unnecessarily spam the API if the
credentials are genuinely expired.
