>       final List<DatanodeDescriptor> live = new ArrayList<DatanodeDescriptor>();
>       final List<DatanodeDescriptor> dead = new ArrayList<DatanodeDescriptor>();
>       blockManager.getDatanodeManager().fetchDatanodes(live, dead, false);
>       out.println("Live Datanodes: "+live.size());
>       out.println("Dead Datanodes: "+dead.size());
>       blockManager.metaSave(out);
> {code}
> Logically all the dataNode related logic can be moved to BlockManager.
> So, here metaSave API is getting the DataNodes details from blockManager to FsNameSystem
and after printing the details again it is giving the control to blockManager.
> It will be good to move the DNs size printing code also to BlockManager.
