Value: fair

    You can use the following property to enable size-based weighting of resource allocation. When this property is set to true, queue resources are assigned to individual applications based on their size, rather than providing an equal share of queue resources to all applications regardless of size. The default setting is false.

    Name: yarn.scheduler.capacity.<queue-path>
Value: true
