--------------------------------------------------------------
I upload a simple patch which made minor change in RouterRPCServer, so that we
can use "hdfs dfsadmin -Dfs.defaultFs=hdfs://{router-union}
-refreshSuperUserGroupsConfiguration" to refresh proxyuser info for RBF:Routers.
Or, I also considered to add a command in dfsrouteradmin shell to
refreshSuperUserGroupsConfiguration independently for routers.
Would you please have a look at this jira?? [~linyiqun] [~eddyxu]
