> Currently in Capacity Scheduler, cluster capacity is divided among the queues
> based on the queue capacity. These queues typically represent an organization
> and the capacity of the queue represents the capacity the organization is
> entitled to. Most organizations are large and need to divide their capacity
> among sub-organizations they have. Or they may want to divide the capacity
> based on a category or type of jobs they run. This JIRA covers the
> requirements and other details to provide the above feature.
