http://hadoop.apache.org/docs/r1.0.4/hdfs_user_guide.html#Backup+Node

the document write:
The Backup node is configured in the same manner as the Checkpoint node. It
is started with bin/hdfs namenode -checkpoint

but hadoop 1.0.4 there is no hdfs file:
[zhouhh@Hadoop48 hadoop-1.0.4]$ ls bin
hadoop            hadoop-daemons.sh  start-all.sh
start-jobhistoryserver.sh  stop-balancer.sh          stop-mapred.sh

       stop-dfs.sh               task-controller
hadoop-daemon.sh  slaves.sh          start-dfs.sh       stop-all.sh

This is a documentation bug. Backup node is not available in 1.x release. It is available in 0.23 and 2.x releases. Please create a bug to point 1.x documents to the right set of docs.

I'd already addressed this via
https://issues.apache.org/jira/browse/HADOOP-7297 and it isn't present
