Subject wrong in secondary namenode ?
Date Wed, 12 Oct 2011 21:32:54 GMT
hi hadoopers,

just want to check how it looks in your hadoop settings.
i am running Cloudera CDH3u0, and really curious why previous.checkpoint
directory is not there.
I haven't set any of fs.checkpoint.period or fs.checkpoint.size.

from Tom White's book, in ${fs.checkpoint.dir} should have current and
previous.checkpoint directories

this is from hdfs-site.xml
<property>
    <name>dfs.name.dir</name>
    <value>/hadoop/name,/hadoop/backup</value>
  </property>
...
...
<property>
    <name>fs.checkpoint.dir</name>
    <value>/hadoop/namesecondary</value>
  </property>


and here is from secondary namenode
[namesecondary]$ pwd
/hadoop/namesecondary

[namesecondary]$ ls
current  image  in_use.lock


hope this make sense
