HDFS can achieve massive data storage management, with the advantages of scalability, high reliability and low cost, which makes the HDFS one of the hotspots in cloud storage. However, only one of HDFS cluster Namenode node would provide metadata services for distributed file system. With the amount of data continues to increase, a single Namenode will encounter the bottleneck problem of performance. According to the HDFS single point problems, this paper presents a distributed multi-Namenode model which could decentralize the ser-vices of distributed file system metadata to several Namenodes.
