Hello,
I'm in the trying to figure out how to decommission data nodes. Here's what
I do:
In hdfs-site.xml I have:
dfs.hosts.exclude
/opt/hadoop/hadoop-1.0.0/conf/exclude
Add to exclude file:
host1
host2
Then I run 'hadoop dfsadmin -refreshNodes'. On the web interface the two
nodes n
Your nodes need to be in include and exclude file in the same time
Do you use both files?

Do you mean the file specified by the 'dfs.hosts' parameter? That is not
currently set in my configuration (the hosts are only specified in the
slaves file).

Thanks, this seems to work now.
Note that the parameter is 'dfs.hosts' instead of 'dfs.hosts.include'.
(Also, the normal caveats like hostnames are case sensitive).
