With the extensive application of cloud storage,distributed file system is considered as a key of cloud storage,attracts increasing attention.This paper describes the performance characteristics of 5 kinds of major open-source distributed file system,and I / O performance is improved on HDFS,the system architecture,access methods,storage and other aspects of server distribated file systems are compared in order to select the appropriate distributed file system.Experimental results show,improved HDFS is great improved in high memory usage,and also slightly faster than Lustre in data read.
