Decomssion datanode - no response
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?
