Description

When we schedule in multi node lookup policy for async scheduling, or just use heartbeat update based scheduling, we both meet scheduling fragments. When cpu-intensive jobs or gpu-intensive or memory-intensive etc, the cluster will meet heavy waste of resources, so this issue will help to move scheduler support dominant resource based schedule, to help our cluster get better resource utilization, also in order to load balance nodemanager resource distribution.
