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" *

You can get these logs in Name node logs.

I am seeing this log on the screen when running from my client (hadoop

.net.ConnectException: Connection refused

 

I can't find where the logs are for this hadoop client process run to
see what machine it is having trouble connecting to so I can run the
standard debugging to see why that port is not available on that
machine, but I don't know which port or which machine it's trying to
reach.  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.

 

Anyways, any ideas,

Thanks,

Dean
