-------------------------------------------------------------------------
Key: MAPREDUCE-1678
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1678
Project: Hadoop Map/Reduce
Issue Type: New Feature
Components: job submission
Reporter: Kyle Ellrott
Priority: Trivial
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);
}
}
