Afraid not. (that was the first thing I tried) My only grep of Connection is (guess I have to go into debug mode and fiddle around there).
[r...@dnvr-dev3 logs]# grep "Connection" * hadoop-root-namenode-DNVR-DEV3.log:2011-01-04 02:30:58,180 INFO org.apache.hadoo p.ipc.Server: IPC Server listener on 54310: readAndProcess threw exception java. io.IOException: Connection reset by peer.

Any idea where those lots are? Also, if developers could add a try{}catch(ConnectionRefused) rethrow new ConnectionRefused("Connection to <machine> <port> refused", e), that would rock so it would have just shown up in my hadoop client's log file.
