> 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}
