Description

TestResourceManager rely on the capacity scheduler.

It relies on a scheduler that assigns multiple containers in a single heartbeat, which not all schedulers do by default. It also relies on schedulers that don't consider CPU capacities. It would be simple to change the test to use multiple heartbeats and increase the vcore capacities of the nodes in the test.
