摘要

近年来,云计算日益成为国内外关注的焦点。当大数据存储成为云计算系统的核心时,云计算系统将演变为云存储系统。随着云计算的迅速发展,云存储已成为当今最热门的研究领域之一。HDFS (Hadoop Distributed File System)为云存储系统提供了强大的数据存储能力。但由于在设计过程中存在一定的缺陷,在大规模应用前必须对其进行改进。研究了基于HDFS的云存储模型,解决了副本分布不均匀的问题。

Research and improvement of HDFS
Recently, cloud computing is increasingly becoming the focus of attention at home and abroad. When the big data storage is become the core of cloud computing system, cloud computing system would evolve into a cloud storage system. With rapidly development of cloud computing, cloud storage has become one of most popular research field. HDFS (Hadoop Distributed File System) has a powerful data storage capacity for cloud storage system. However, it must be improved before applied to large scale since it exists some drawbacks during the design process. This paper researches the cloud storage model based on HDFS, solves uneven replica distribution.
