after above two step now we can configure our hadoop
at first we must install the "jdk" and then we can install hadoop
1. install jdk
    i use the command "sudo apt-get install openjdk-7-jdk"
    and you can down the new jdk package and install it
2. down the hadoop package  at below url
     />     and you can search "hadoop releases" by google to find
3. install and configure the file
    (1 install it
    uncompress the package
    at the "Downloads" directory use the below commands
    "tar-vxzf hadoop-2.6.0.tar.gz -C /home/warrior/bigData"
    "cd /home/warrior/bigData"
    "mv hadoop-2.6.0 hadoop"
    (2 configure it 
    at first set the "/etc/profile"
    add the content
