3. Hierarchical Queue Characteristics

  • 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.
