My original names where huey-direct and duey-direct, both names in
the /etc/hosts file on both machines.
Are nn.internal and jt.interal special names?

David,
For the Option #1.
I just changed the names to the IP Addresses, and it still comes up
as the external name and ip address in the log files, and on the
job tracker screen.
So option 1 is a no go.
When I change the "dfs.datanode.dns.interface" values it doesn't
seem to do anything. When I was search archived mail, this seemed
to be a the approach to change the NIC card being used for
resolution. But when I change it nothing happens, I even put in
bogus values and still no issues.

I've been having similar but different fun with Hadoop-on-VMs,
there's a lot of assumption that DNS and rDNS all works consistently
in the code. Do you have separate internal and external hostnames?
In which case, can you bring up the job tracker as jt.internal ,
namenode as nn.internal (so the full HDFS URl is something like
hdfs://nn.internal/ ) , etc, etc.?
