=D6=F7=CC=E2: 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</valu= e>
  </property>

 

then:

hdfs dfsadmin -refreshNodes<= /u>

 

but there is no decomssion node= s showed on the webUI. and not any releated logs in the datanode log. what'= s wrong?
