---------------------------------

             Summary: Add capacity-scheduler-default.xml to provide a default 
set of configurations for the capacity scheduler.
                 Key: YARN-140
                 URL: https://issues.apache.org/jira/browse/YARN-140
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler
            Reporter: Ahmed Radwan
            Assignee: Ahmed Radwan


When setting up the capacity scheduler users are faced with problems like:

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

Which basically arises from missing basic configurations, which in many cases, 
there is no need to explicitly provide, and a default configuration will be 
sufficient. For example, to address the error above, the user need to add a 
capacity of 100 to the root queue.

So, we need to add a capacity-scheduler-default.xml, this will be helpful to 
provide the basic set of default configurations required to run the capacity 
scheduler. The user can still override existing configurations or provide new 
ones in capacity-scheduler.xml. This is similar to *-default.xml vs *-site.xml 
for yarn, core, mapred, hdfs, etc.
