Hierarchical queue characteristics

You must consider the various characteristics of the Capacity Scheduler hierarchical queues before setting them up.

There are two types of queues: parent queues and leaf queues.

• Parent queues enable the management of resources across organizations and sub- organizations. They can contain more parent queues or leaf queues. They do not themselves accept any application submissions directly.

• Leaf queues are the queues that live under a parent queue and accept applications. Leaf queues do not have any

  child queues, and therefore do not have any configuration property that ends with ".queues".

• There is a top-level parent root queue that does not belong to any organization, but instead represents the cluster itself.

• Using parent and leaf queues, administrators can specify capacity allocations for various organizations and sub-organizations.
