Virtual Machines are a mainstay in the enterprise. Apache Hadoop is normally run on bare machines. This talk walks through the convergence and the use of virtual machines for running ApacheHadoop. We describe the results from various tests and benchmarks which show that the overhead of using VMs is small. This is a small price to pay for the advantages offered by virtualization. The second half of talk compares multi-tenancy with VMs versus multi-tenancy of with Hadoop`s Capacity scheduler. We follow on with a comparison of resource management in V-Sphere and the finer grained resource management and scheduling in NextGen MapReduce. NextGen MapReduce supports a general notion of a container (such as a process, jvm, virtual machine etc) in which tasks are run;. We compare the role of such first class VM support in Hadoop.
