摘要
Abstract
Since the public cloud storage exisits the unsafe factors of data leakage,data lose and unstable storage,the pri-vate cloud storage becomes the best choice to meet the current safety storage demands of the enterprises. To solve the too high load of the single point memory and low writing efficiency,a module to deal with the massive small files was designed. Multiple small files are merged through the cache,and the index table is placed into the metadata of the emerged file. The method of finding small file data in the block by means of the offset in the index table can improve the HDFS performance of writing mas-sive small files. The validity of the optimization scheme was verified with an experiment.关键词
