> After YARN-3983, we have an extensible ContainerAllocator which can be used by FiCaSchedulerApp
to decide how to allocate resources.
> While working on YARN-1651 (allocate resource to increase container), I found one thing
in existing logic not flexible enough:
> - ContainerAllocator decides what to allocate for a given node and priority: To support
different kinds of resource allocation, for example, priority as weight / skip priority or
not, etc. It's better to let ContainerAllocator to choose how to order pending resource requests.
