airflow scheduler default 0 - CrashLoopBackOff

[Unpaired7184]

Affected Stackable version

26.7.0

Affected Apache Airflow version

3.2.2

Current and expected behavior

I'm experiencing the issue described and solved here:
Fix scheduler crashloop from KubernetesExecutor completed-pod adoption- #67850

This is caused by a bug in Airflows cncf-kubernetes provider 10.17.1 (apache-airflow-providers-cncf-kubernetes==10.17.1) wich is used in stackable v26.7.0 with airflow 3.2.2.

Possible solution

Possible solution is to update Airflows cncf-kubernetes provider to 18.0.0 or newer (apache-airflow-providers-cncf-kubernetes>=10.18.0).

Thanks for the report. Can you, as a workaround, for now fall back to Airflow 3.0.6?
https://hub.stackable.tech/releases/26.7

I'll schedule this as a backport for 26.11 where 3.2.2 will still ship but almost certainly as a deprecated version.
This is already fixed in 3.3.

We don't have plans for a patch release right now to backport this to 26.7, if this is urgent please reach out to us directly and we'll see if we can provide a custom image for you, we usually to that only for paying customers or partners.
