Xuan Gong commented on YARN-1766:
---------------------------------

modify the testcase to validate default values for queue config, admin-acls, 
proxy-config, exclude-nodelists, SuperGroupMapping and user-to-groups mapping.
Also, manually call refreshSuperUserGroupsConfiguration when RM does the 
initiation. 

> When RM does the initiation, it should use loaded Configuration instead of 
> bootstrap configuration.

> Right now, we have FileSystemBasedConfigurationProvider to let Users upload 
> the configurations into remote File System, and let different RMs share the 
> same configurations.  During the initiation, RM will load the configurations 
> from Remote File System. So when RM initiates the services, it should use the 
> loaded Configurations instead of using the bootstrap configurations.
