We can create another ticket for adding hdfs-rbf-default.xml in 
HdfsConfiguration, but wondering how it will work for NameNode? Because in a 
namenode scenario, hdfs-rbf-default.xml  may not be in the classpath.

If the XML is non-existing, {{Configuration}} just goes through with it.
Weirdly enough I didn't even see it throwing a warning or anything.
Anyway, we can discuss further in the new JIRA as it has a lot of smalls issues 
with the default values.
