The performance of three Hadoop applications is reported for several virtual configurations on VMware vSphere 5 and compared to native configurations. A well-balanced seven-node AMAX ClusterMax system was used to show that the average performance difference between native and the simplest virtualized configurations is only 4%. Further, the flexibility enabled by virtualization to create multiple Hadoop nodes per host can be used to achieve performance significantly better than native.
