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?

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.

Subject: 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?

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.

主题: 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?

It's 20 minutes passed after I ran -refreshNodes, but there is no
decomssion nodes showed on the UI. and canno find any hints in the NN and
DN logs.

I know the default value is 10 minutes and 30 seconds for switching
datanodes from live to dead.

主题: 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?
RE: Decomssion datanode - no response

Do you see any log related to this in Name Node logs when you issue refreshNodes dfsadmin command?
Thanks
