Resource allocation overview
You can allocate resources to queues by using either the Absolute allocation mode, in which the actual units of vCores and memory resources are allocated, or the Relative allocation mode, in which resources are allocated as a percentage of total resources.
- Relative mode: In the YARN Queue Manager UI, the capacity value is shown as a percentage. When editing queue resources, capacities are specified in percentages. The capacity allocated to a set of sibling queues must equal 100% of the parent.
- Absolute mode: In the YARN Queue Manager UI, the capacity value is shown in units. When editing queue resources, a separate tab is displayed for each resource type. The total allocated capacity must be less than or equal to the capacity of the parent.
