Research Of Cluster Triplet-Space

Triplet Space include Unified Space,Users'Space,Physical Space. It is a cluster space model formed little by little with the dissection of HDFS.HDFS is Hadoop Distributed File System, and Hadoop is the framework which is wide used in cloud computing.By dissecting HDFS,we got a instance of triplet Space,but as a concept, the triplet Space is not the equivalent of any specific operation system.To distinguish from triplet Space formed in HDFS, we propose general triplet Space. Infinite is not excluded in general triplet Space, but there are limited point in HDFS triplet Space for instace:Max table(Mb),Max tree(Mt),it determine that HDFS is only implement of triplet Space on level of finite. Focus on the cause of limit point in HDFS, this paper approach some directions to implement infinite cluster triplet Space,one of it is a function base on Mapreduce named MapG,another is a infinite cluster triplet Space model—Ring Space.
