Description

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
hadoop-config.sh rcc start-balancer.sh start-mapred.sh stop-dfs.sh task-controller
hadoop-daemon.sh slaves.sh start-dfs.sh stop-all.sh stop-jobhistoryserver.sh

[zhouhh@Hadoop48 hadoop-1.0.4]$ find . -name hdfs
./webapps/hdfs
./src/webapps/hdfs
./src/test/org/apache/hadoop/hdfs
./src/test/system/aop/org/apache/hadoop/hdfs
./src/test/system/java/org/apache/hadoop/hdfs
./src/hdfs
./src/hdfs/org/apache/hadoop/hdfs

1.x does not support backup node, so there is a bug
