If you have ad= ded this configuration after starting NN, it won=92t take effect and need t= o restart NN.

If you have added th= is config with the exclude file before NN start, you can update the file wi= th new hosts and refreshNodes command can be issued, then newly updated the DN=92s will be decommissioned.

Hi,

I am using hadoop-2.0.5-alpha, and I added 5 datanod= es into dfs_exclude,

=A0

hdfs-site.xml:

=A0 <property>
=A0=A0=A0 <name>dfs.hosts.exclude</name>
=A0=A0=A0 <value>/usr/local/hadoop/conf/dfs_exclude</value>
=A0 </property>

=A0

then:

hdfs dfsadmin -refreshNodes

=A0

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

=A0
