> The current YARN resource management logic assumes resource allocated to a container is fixed during the lifetime of it. When users want to change a resource
> of an allocated container the only way is releasing it and allocating a new container with expected size.
> Allowing run-time changing resources of an allocated container will give us better control of resource usage in application side
