Data transfer path recommend method and system in the virtual MapReduce

摘要

The present invention relates to a method and system for recommending a data transmission path in a virtual mapleuse cluster, and more particularly, to a method and system for recommending a data transmission path in a virtual mapleuse cluster in which data is transmitted between a mapper virtual machine and a reducer virtual machine mounted on a physical machine Wherein the resource utilization rate acquisition unit acquires a resource utilization rate of the virtual machine and the driver domain; Estimating and calculating a data transmission time through a plurality of data transmission paths between the mapper virtual machine and the reducer virtual machine based on the resource utilization rate of the virtual machine and the driver domain and the data size to be transmitted; And a step of searching for a data transmission path corresponding to a minimum time of the data transmission time computed by the data transmission path recommendation section and recommending the retrieved data transmission path as an optimal data transmission path between the mapper virtual machine and the reducer virtual machine . With this configuration, the data transfer path recommendation method and system in the virtual map devise cluster of the present invention can dynamically detach a block device attached to a virtual machine and then reattach to another virtual machine for a runtime It is possible to easily and quickly transfer data without any network transmission between virtual machines.
