--------------------------------------------------------------
Again, the notion of capacity-scheduler-default.xml overridden by
capacity-scheduler-site.xml _does not_ make sense for CapacityScheduler - this
has been the case for a *very long* time.
-1 for *-default.xml + *-site.xml for the CS.
A simpler 'fix' for the problem at hand is to hard-code root capacity to 100,
and provide sane defaults in code for the rest.

> 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.
