Perform the following steps to set up a Hadoop environment using the Cloudera QuickStart VM:
- Visit the Cloudera QuickStart VM download site (you may need to update the link as Cloudera upgrades its VMs; the current version of CDH is 5.3) at http://www.cloudera.com/content/cloudera/en/downloads/quickstart_vms/cdh-5-3-x.html:

- Depending on the virtual machine platform installed on your OS, choose the appropriate link (you may need to update the link as Cloudera upgrades its VMs) to download the VM file:
- To download VMWare: You can visit https://downloads.cloudera.com/demo_vm/vmware/cloudera-quickstart-vm-5.2.0-0-vmware.7z
- To download KVM: You can visit https://downloads.cloudera.com/demo_vm/kvm/cloudera-quickstart-vm-5.2.0-0-kvm.7z
- To download VirtualBox: You can visit https://downloads.cloudera.com/demo_vm/virtualbox/cloudera-quickstart-vm-5.2.0-0-virtualbox.7z
- Next, you can start the QuickStart VM using the virtual machine platform installed on your OS. You should see the desktop of Centos 6.2 in a few minutes:
