Remove LLAP Queue

Before upgrading from HDP to CDP, if you used LLAP, a YARN interactive query queue was created. This queue is carried over to your CDP cluster. You must remove this queue, likely named llap, after the upgrade.

When you set up LLAP in an HDP cluster, Ambari creates a queue named llap by default; however, you might have created the LLAP queue manually and assigned it a different name.
  1. In Cloudera Manager, select Clusters > YARN > YARN Queue Manager UI.
    A graphical queue hierarchy is displayed in the Overview tab.
  2. Click the options menu for the interactive query queue.
  3. Click Delete Queue, and confirm deletion.
