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

Thanx [~aajisaka] for the report. Indeed That is something missing, though cost 
to restart router is low, But still this is good to have.

> RBF: Add dfsrouteradmin -refreshSuperUserGroupsConfiguration command option

> NameNode can update proxyuser config by -refreshSuperUserGroupsConfiguration 
> without restarting but DFSRouter cannot. It would be better for DFSRouter to 
> have such functionality to be compatible with NameNode.
