Relaying cloud establishing method based on virtualized Hadoop cluster

The invention discloses a relaying cloud establishing method based on a virtualized Hadoop cluster. The method comprises the steps of (1) virtualizing hardware resources of a computer server through the installation of a Hyper-V Server system; (2) establishing a virtual machine cluster by means of Hyper-V Client, and installing the Win7 operating system for each virtual machine; (3) realizing Hadoop under the Windows platform by means of Cygwin, integrating the established virtual machine cluster, and building a cloud computing platform; (4) determining a master virtual node and a slave virtual node at the cloud end, deploying a relaying setting calculation system and a task distributing program on the master node in a service mode, deploying and executing the program of a parallel task on the slave node, and then realizing the mode of software namely a service.
