I want to remove nodes from my cluster *gracefully*. I added the following
lines to my hdfs-site.xml
In exclude file i have mentioned the hostname of the datanode.
Then I run 'hadoop dfsadmin -refreshNodes'
On the web interface the node now appear in both the 'Live Node' and
'Dead Node' (but there's nothing in the Decommissioning Node list).
What am I missing during the decommission process?
