CLUSTER

On a first stage, four virtual machines were deployed on a private OpenNebula cloud environment, placed on CSUC facilities. That configuration allowed to get expertise in the installation and management of CDH, the popular Apache Hadoop distribution. Some programming and performing analysis were executed, which revealed the need to go further and deploy the system using physical machines.
