Description

A queue named "root.root" may cause issue in Fair scheduler. For example, if we set the queue(root.root) to be reservable, then submit a job into the queue. We got following error.

java.io.IOException: org.apache.hadoop.yarn.exceptions.YarnException: Failed to submit application_1508176133973_0002 to YARN : root.root is not a leaf queue
