Converting a queue to a Managed Parent Queue

In absolute and relative modes, you have to create Managed Parent Queues to enable dynamic queue creation. You can do that through the YARN Queue Manager UI.

Note that the queue properties that is set at the Managed Parent Queue level is applied to all of its leaf queues.
  1. In Cloudera Manager, select the YARN Queue Manager UI.
    A graphical queue hierarchy is displayed in the Overview tab.
  2. Find the queue for which you want to enable the dynamic child creation feature.
  3. Select the More Options menu and select Enable Dynamic Child Creation.
  4. Set the Minimum and Maximum capacities that will be applied for every dynamic child queue under that particular parent queue.

    Save the minimum and maximum capacity for the queue with the default values that copy the parent queue, or change them using the Auto Queue Creation template (Technical Preview) feature.

    Technical Preview: This is a technical preview feature and considered under development. Do not use this in your production systems.

  5. Click Save.
To define a placement rule that could lead to dynamically created child queues, ensure that during placement rule creation you select the Create the target queue if it does not exist? option and provide a Managed Parent Queue as the parent queue. For more information, see Manage placement rules.
