I imagine that the access to the ports used by HDFS could be restricted to specific IPs using the EC2 group (ec2-authorize) or any other firewall mechanism if necessary. Could anyone confirm that there is no conf parameter I could use to force the address of my DataNodes? Thanks Julien -- DigitalPebble Ltd http://www.digitalpebble.com
