In this paper, we propose the distributed cache management scheme to efficiently access small files in Hadoop Distributed File Systems(HDFS). The proposed scheme can reduce the number of metadata managed by a name node since many small files are merged and stored in a chunk. It is also possible to reduce the file access costs, by keeping the information of requested files using the client cache and data node caches. The client cache keeps small files that a user requests and metadata. Each data
