That is what I thought also, is that it needs to keep that information
somewhere, because it needs to be able to communicate with all of the
servers.
So I deleted the /tmp/had* and /tmp/hs* directories, removed the log
files, and grepped for the duey name in all files in config. And the
problem still exists. Originally I thought that it might have had
something to do with multiple entries in the .ssh/authorized_keys file
but removed everything there. And the problem still existed.
So I think that I am going to grab a new install of hadoop 0.19.1,
delete the existing one and start out fresh to see if that changes
anything.
Wish me luck:)

Does hadoop "cache" the server names anywhere? Because I changed

it is trying to view with the old name. And I changed the hadoop-

in SVN head, we try and get Java to tell us what is going on
http://svn.apache.org/viewvc/hadoop/core/trunk/src/core/org/apache/hadoop/net/DNS.java
This uses InetAddress.getLocalHost().getCanonicalHostName() to get
the value, which is cached for life of the process. I don't know of
anything else, but wouldn't be surprised -the Namenode has to
remember the machines where stuff was stored.
