10.1. How to refresh the YARN Capacity Scheduler

This topic describes how to refresh the Capacity Scheduler in cases where you have added or modified existing queues.

  • In Ambari Web, browse to Services > YARN > Summary.

  • Select Service Actions, then choose Refresh YARN Capacity Scheduler.

  • Confirm you would like to perform this operation.

    The refresh operation is submitted to the YARN ResourceManager.


The Refresh operation will fail with the following message: “Failed to re-init queues” if you attempt to refresh queues in a case where you performed a destructive change, such as removing a queue. In cases where you have made destructive changes, you must perform a ResourceManager restart for the capacity scheduler change to take effect.
