> Change methods in org.apache.hadoop.mapreduce.Cluster from private to protected to allow
extension of cluster.
> If the method createRPCProxy is changed from private to protected, then alternate cluster
implementations could be written that return other ClientProtocol's. 
> For example, changing the protocol some custom implementation called SimpleClient
>  
> ie:
> public class SimpleCluster extends Cluster {
>   @Override
>   protected ClientProtocol createRPCProxy(InetSocketAddress addr, Configuration conf)
throws IOException {
>     return new SimpleClient(conf);
>   } 
> }
