Dynamic De-duplication Decision in  a  Hadoop Distributed File System

Ruay- Shiung Chang ,  Senior Member, IEEE ,  Chih - Shan Liao, Kuo- Zheng Fan,  and  Chia - Ming Wu  

In this paper, we propose a dynamic De - duplication decision to improve  the storage  utilization  of a datacenter  which  uses   HDFS  as its file system.  Our  proposed  syst em  can formulate a proper De-duplication strategy   to sufficiently utilize the storage space under the  limited storage   devices. Our De-duplication strategy deletes useless duplicates to increase the storage space.
