我的 hadoop 启动了，但我的 hadoop 命令都没有工作。

starting:

hduser@reshmi-Inspiron-1545:~$ cd hadoop-1.0.4/bin/
hduser@reshmi-Inspiron-1545:~/hadoop-1.0.4/bin$ ./start-all.sh 
Warning: $HADOOP_HOME is deprecated.

The hadoop command is not found because it is not specified in your PATH variable. Try this:

export PATH=$PATH:~/hadoop-1.0.4/bin/
