Hey David,
Look at the web interface. Here's mine:
http://dcache-head.unl.edu:8088/dfshealth.jsp
The "admin state" column says "in service" for normal nodes, and
"decommissioning in progress" for the rest. When the decommissioning
is done, the nodes will migrate to the list of "dead nodes" and shut
themselves off. Only then can you safely turn off nodes.

I'm starting to think I'm doing things wrong.
I have an absolute path to dfs.hosts.exclude that includes what i want
decommissioned, and a dfs.hosts which includes those i want to remain
commissioned (this points to the slaves file).
Nothing seems to do anything...
What am I missing?

Hi,
I'm trying to decommission some nodes. The process I tried to
follow is:
1) add them to conf/excluding (hadoop-site points there)
2) invoke hadoop dfsadmin -refreshNodes
This returns immediately, so I thought it was done, so i killed off
the cluster and rebooted without the new nodes, but then fsck was
very
unhappy...
Is there some way to watch the progress of decomissioning?
Thanks,
-- David
