The last form is required when specifying resources other than memory and CPU. In the last form, X and Y can either be a percentage or an integer resource value without units. In the latter case the units will be inferred from the default units configured for that resource. A queue will not be assigned a container that would put its aggregate usage over this limit.

The latter form is required when specifying resources other than memory and CPU. If the property is not set it's value is inherited from a parent queue. It's default value is **yarn.scheduler.maximum-allocation-mb**. Cannot be higher than **maxResources**. This property is invalid for root queue.
