Decommission a DataNode from a running Hadoop Cluster
Hello,
I need to decommission a datanode from a running cluster, my probleme is
that the "dfs.hosts.exclude" property was not set on either the
"hdfs-site.xml" nor the "core-site.xml", and since adding it requires an
HDFS restart (which I can't do). How do I decommission that datanode ?

Hello,
Seems like I was updating the "hdfs-site.xml" on the datanode I want to
decommission instead of the namenode. I added the exclude property in the
"hdfs-site.xml" on the namenode, executed the refresh command and it worked
without restarting the cluster... it is now decommissioning.
Please ignore my previous email.
Thank you.
