Hadoop Virtual Machine

Practical exercices will be held in a laboratory using virtual machines replicated on a VMware cluster.

Virtual machine details:

• it preconfigured with all the software needed to get through the assignments.
• it has an ubuntu 12.04 LTE (64bit) with XFCE
• it requires >=2GB of memory
• it has a single account:
  • username: student
  • password: password
  • Notice that login is password less and root commands can be run using sudo which is password less as well.

Run the virtual machine at the LAB:

• Each student will access to a dedicated image using one Windows PCs of the LAB.
  • Login on a PC using the credentials found in the course material. At the first access it will be requested to change the password
  • click on the windows start menu and type \\linfa\coreapp\VMware to connect to remote disk
  • run "VMware vSphere Client"
  • enter in IP address/Name field vcenter.polito.it and check "use window session credentials"
  • select vmware templates and then datacenter -> corsi -> bigdata
  • right click on the LinuxXYZ displayed (corresponding to the specific user's VM image) and select "open console"
  • run "play" to run the virtual machine (in case it does not automatically start).
• To set the full screen mode:
  • either select view-> enter full screen mode or press CTRL+ALT+ENTER when the focus is on the player (the same hotkeys to exit from the full screen)
• To increase the resolution to fit the monitor size:
  • applications menu -> settings -> settings manager -> display
  • change resolution: 1280x768 -> 1600x1050
  • Note: X server will be restarted and will be requested to login again
• Before leaving the LAB, remember to:
  • shutdown the virtual machine
  • exit the window session

Run the virtual machine on the laptop:

• Download the image tarball from here and uncompress it
• To run the image it can be used either VMplayer or Virtualbox
  • VMplayer:
    • Windows/Linux: download the freeware player from here
    • Mac OS: unfortunately there is no freeware player, but it can be used VMware Fusion which has a 30-day trial. Download available here
  • Virtualbox:
    • The image can be loaded in Virtualbox with no issues. Be sure to select the file HadoopVM.vmdk as a virtual hard-drive (and not one of the HadoopVM-sXXX.vmdk files).
    • To install guest additions, once the image is running:
      • sudo apt-get install dkms build-essential
      • download the additions (devices->install guest additions)
      • cd /media/VIRTUALBOXADDITION_version
      • sudo su -
      • ./VBoxLinuxAddition.run
