> Resource requirements for each tasks are varied but currently it's fixed to one value(via
hive.tez.container.size). It would be good to customize resource requirements appropriate
to expected work.
> Suggested interface is quite simple.

> public interface ResourceCalculator {
>   Resource adjust(Resource resource, MapWork mapWork);
>   Resource adjust(Resource resource, ReduceWork reduceWork);
> }
> {code}
