Should we set a default value for this ? Current behavior is when no set, gc will not delete Job.

Yes, we should set default for this in admission controller.

In which case, we need to do a double check ?

There a lots of codes:
status.State.LastTransitionTime = metav1.Now()
which can be upgraded into a function which used to update status and update the LastTransitionTime when required.

I think we should add the validation as it should not be negative value. we can add the same in validateJob() func.

validate can be applied in admission controller
