Description

This is basically to address the error:

FATAL org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Error starting ResourceManager
java.lang.IllegalArgumentException: Illegal capacity of -1 for queue root

Which the user gets if the capacity for the root queue is not explicitly specified in the capacity-scheduler.xml
