中文摘要：

本文对目前代表性的云计算技术进行了回顾,选择其中的HDFS提取主要组成元素分析整理,抽象出若干对象集和关系集,进而提出集群三元空间。从抽象层面回归到具体实现,HDFS对集群三元空间的实现采用了集中式结构,形成了系统性能的瓶颈以及集群扩展的滞点。集群三元空间从抽象层面,剔除具体实现因素之后,给出了系统分析与问题定义的背景。

英文摘要：

Review the typical cloud computing technology,HDFS is singled out to research.By analysing its elements we abstract several object sets and relation sets,even more we propose the concept of cluster riplet-space.Regress to implement from abstract level,HDFS use a centralization structure to implement cluster triplet-space that form the bottleneck of system performance and stagnation point of cluster.By rejecting the specific implementation,triplet-space construct a setting to define question on abstract level.
