      Description

      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.
