Resource allocation overview

You can allocate resources to queues by using either the Absolute mode, in which the actual units of vCores and memory resources are allocated, the Relative mode, in which resources are allocated as a percentage of total resources, or in the Weight mode, in which resources are allocated as a fraction 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.
Weight mode: In the YARN Queue Manager UI, the capacity value is shown as a numerical value and is suffixed with “w”. For example, 5w. When editing queue resources, capacities are specified in weights or fractions of total resources. The resources are divided based on how the queue's weight relates to the sum of configured weights under the parent.
note
If you have an existing managed queue in Relative mode, then conversion to Weight mode is not allowed. You must delete the managed parent queue and then convert from Relative mode to Weight mode.
