> 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);
> }
