> We would like to use Yunikorn's gang scheduling feature to schedule ML training jobs for different teams. We want to give each team a quota and allow them to borrow resources from other teams' quotas, but have their job preempted if the other team needs to use those resources. However, this seems to not be supported currently, as Yunikorn is missing application-level preemption. It will preempt individual pods until it has freed up enough resources, and those pods may not be from the same application. This is an issue for us because our training jobs are not fault-tolerant and will die if 1 pod gets killed, so we want to preempt an entire application at the same time.
