Error running Mapreduce in Eclipse using hadoop

Hi,
I have installed Eclipse SDK 3.3 on my machine. Also I have the Apache hadoop version 1.0.4 installed in my plug-in directory. I am trying to add the server to run Mapreduce on with the following details -
Server Name: CMU Cluster 
Hostname: 10.1.133.44 
Installation directory: /hadoop/hadoop-0.13.1 
username: (your username) 
Select Tunnel Connections 
Tunnel via: hadoop.cs.washington.edu 
Tunnel username: (your username) 
But when I click the 'Validate Location' tab, I get an error stating "Problems connecting to server: java.net.UnknownHostException: hadoop.cs.washington.edu"
I can SSH into the specified machine / cluster and run the map reduce from there. 
I cannot understand what the problem is. I have attached a screen shot of the error if that helps.
Thank you in advance.
Regards,
