Continued from Getting started with Hadoop Configuration # 1...
The installation of Ubuntu on the Virtual environment begins....
It shall takes time to install Ubuntu & configure it files in the Virtual environment, after the successful installation, the following screen appears for you to login to the environment..
Enter the password, the Root user is enabled; to change the password for the root user as follows,
root@ubuntu:~# sudo passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
The next steps in Hadoop configuration is to install the pre-requisites for Hadoop and install hadoop which shall be followed very soon....
Catch u later..
The installation of Ubuntu on the Virtual environment begins....
Login to Ubuntu environment with the user name and password, after the successful login, change the display settings to be in the appropriate screen resolution whichever you are comfortable.
Please note that the user that you have created is not the "Root" user for the administrator however for hadoop configuration and subsequent operations, the root user privilege shall be required.
- For the benefit of new users to Unix/Linux, a quick intro to "root" is that it is the super user name similar to that of administrator group in Windows environment.
- By default, the Root user is disabled in the Ubuntu environment so that no one logins directly as root as it might be risky if you accidentally execute a wrong command incorrectly and destroy the system.
- "sudo" is the command that enables the user to execute certain programs as Root without having to know the root password; which shall also be used to enable the root user.
Hence the first step in the hadoop configuration is to enable to "root".
Open a Terminal in the Ubuntu environment, in case if you are not able to find the Terminal; search for the same by clicking "Dash Home" with the keyword "Terminal". The below screen shall be opened,
Follow the below steps,
ramjir@ubuntu:~$ sudo -i[sudo] password for ramjir:
root@ubuntu:~#Enter the password, the Root user is enabled; to change the password for the root user as follows,
root@ubuntu:~# sudo passwd root
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
The next steps in Hadoop configuration is to install the pre-requisites for Hadoop and install hadoop which shall be followed very soon....
