cloudera vm: A Single-Node Hadoop Cluster and Examples for Easy Learning!

Cloudera Enterprise: The world's most popular Apache Hadoop solution

Cloudera offers the highest performance and lowest cost platform for using data to drive better business outcomes. Cloudera Enterprise makes Hadoop fast, easy, and secure, so you can focus on results.

Cloudera QuickStart VMs are for demo purposes only and are not to be used as a starting point for clusters.

• The VMs run CentOS 6.4 and are available for VMware, VirtualBox, and KVM.
• All require a 64-bit host OS.

Cloudera QuickStart virtual machines (VMs) include everything you need to try CDH, Cloudera Manager, Cloudera Impala, and Cloudera Search.
The VM uses a package-based install. This allows you to work with or without Cloudera Manager. Parcels do not work with the VM unless you first migrate your CDH installation to use parcels. On your production systems, Cloudera recommends that you use parcels.
