Hey Roger,
This sounds vaguely familiar to me. Do you have multiple hostnames or
multiple IPs in that node?
In one of our dual-homed host, I think the sysadmin had to do
something different to decommission it - something like list the IP in
the exclude hosts? I can't remember.

Hello,
I'm having trouble decommissioning nodes in Hadoop. This worked
previously
for me in this version of hadoop (0.18.2) and I cannot pinpoint what
is
wrong. I am adding the host I wish to decommission to the exclude
file
specified in site.xml. I then run refreshNodes on the master.
Rather than
the "Decommission in progress" that I'm used to seeing, it instead
lists the
node both in Live datanodes and Dead Datanodes.
When I go to the DFS health webpage, the only difference I see is
when I
mouseover the node in Live nodes, it appears as IP:PORT in the tooltip
popup. When I mouseover the version of it that appears as dead, it
lists as
HOSTNAME:PORT. These are both the same node, just listed twice.
The port
is the same between both mouseovers.
Does anyone know what I am doing wrong? I checked slaves, and that
node is
only listed once. It's also listed in exclude only once. At no
point do I
have IP addresses listed.
Thanks for any suggestions.
