> The stopDataNode method will shut down the last node in the list of nodes, if
> one matching a specific name is not found
> This is possibly not what was intended. Better to return false or fail in
> some other manner if the named node was not located
> synchronized boolean stopDataNode(String name) {
> int i;
> for (i = 0; i < dataNodes.size(); i++) {
> DataNode dn = dataNodes.get(i).datanode;
> if (dn.dnRegistration.getName().equals(name)) {
> break;
> }
> }
> return stopDataNode(i);
> }
