> when HADOOP-4885 is implemented and committed we will automatic facility to 
> restore failed storage replicas for namenode. Currently it is controlled by 
> configuration file.
> But since it is quite a "sensitive" feature we might want to have a manual 
> way of turning it on. (i.e. starting with the feature turned off, and turn it 
> on when needed).
> we can use hadoop dfsadmin script to do this.
