When did you add this configuration in NN conf?
<property>
<name>dfs.hosts.exclude</name>
<value>/usr/local/hadoop/conf/dfs_exclude</value>
</property>
If you have added this configuration after starting NN, it won't take effect
and need to restart NN.
If you have added this config with the exclude file before NN start, you can
update the file with new hosts and refreshNodes command can be issued, then
newly updated the DN's will be decommissioned.

Hi,
I am using hadoop-2.0.5-alpha, and I added 5 datanodes into dfs_exclude,
hdfs-site.xml:
<property>
<name>dfs.hosts.exclude</name>
<value>/usr/local/hadoop/conf/dfs_exclude</value>
</property>
then:
hdfs dfsadmin -refreshNodes
but there is no decomssion nodes showed on the webUI. and not any releated logs
in the datanode log. what's wrong?
