I'm trying to setup what I think would be a common hadoop
configuration. I have 4 data nodes on an internal 10.x network. Each
of the data nodes only has access to the 10.x network. The name node
has both an internal 10.x network interface and an external interface.
I want the hdfs filesystem and job tracker to be available on the
external network, but the communication within the cluster to be on the
10.x network. Is this possible to do? Changing the fs.default.name
configuration parameter I can change the filesystem to listen from the
internal to the external interface, however, then the data nodes can't
communicate to the name node. I also tried setting the fs.default.name
IP address to to see if it would bind to all interfaces, but
that didn't seem to work.

Is it possible to configure hadoop so that the datanodes communicate
on an internal network, but access to hdfs and the job tracker are done
through an external interface?

Any help would be much appreciated.

Thank you
