followed a weblink and try to install it. I want to install hadoop on my 
single node cluster.

java in /usr/java/jdk1.6.0_24. the step i take to install hadoop are 

1: Make a group hadoop and a user hadoop with home directory
in hadoop directory i have a directory called projects and download 
hadoop binary there than extract them there;
i configured the ssh also.

with this male please check them .
1: hadoop_env_sh
4 hdfs-site. xml
5 hadoop's usre .bashrc

  After making changes to these fie ,I just enter the hadoop account and 
enter the  few command following thing happen :

hadoop@ws40-man-lin:~$ hadoop namenode -format
hadoop: command not found
