Hi, I've got a question about behavior we're seeing.
Two queues: Preemption enabled, CapacityScheduler (happy to provide more config if needed), 50% of resources to each Submit a job to queue 1 which uses 100% of the cluster. Submit a job to queue 2 which doesn't get allocated because there are not enough resources for the AM. I'd have expected this to trigger preemption but it doesn't happen. Is this expected? Second question: Once we get the second job running it only gets three containers but requested six. Utilization at this point is still "unfair" i.e. queue 1 ~75% resources, queue 2 ~25% resources. We saw two preemptions happening to get to this 25% utilization but then no more. Any idea why this could be happening? Thank you! Lars
