--------------------------------

one simple way is enable continuous Scheduling,  allocate containers to the node with least resource not max.

> we had a gpu cluster, jobs with bigger resource request couldn't be satisfied for node is running the jobs with smaller resource request.  we didn't open reserve system because gpu jobs may run days or weeks. we expect scheduler allocate containers to fill the node , then there will be resource to run   jobs with big resource request.
