摘要

近年来，人们提出了各种各样的云存储服务。即使移动设备和手机的存储空间有限，用户也可以通过互联网获得巨大的云存储空间。本文实现了一个基于Apache Hadoop的分布式文件系统，将原有的Hadoop分布式文件系统替换为Tahoe最小权限文件系统。此外，我们还研究了两种不同文件大小下的总传输速率和下载时间。实验结果表明，所建立的文件系统在部分存储节点出现故障的情况下，仍能提供安全可靠的云存储服务。

Implement a reliable and secure cloud distributed file system

In recent years, there are various cloud storage services have been proposed. The users can acquire the enormous cloud storage spaces through Internet even if the storage space of portable devices and handsets are limited. In this paper, we implement a distributed file system based on Apache Hadoop, and the original Hadoop distributed file system is replaced with the Tahoe least-authority file system. Furthermore, we investigate the total transmission rate and download time with two different file size. The experiment result shows that the established file system provides a secure and reliable cloud storage service even if parts of storage nodes are broken.
