             Summary: CapacitySchedulerConfiguration#getCapacity should return 
100.0f for root queue
                 Key: YARN-143
                 URL: https://issues.apache.org/jira/browse/YARN-143
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler
            Reporter: Ahmed Radwan
            Assignee: Ahmed Radwan


This is basically to address the error:

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

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