Abstract:As a distributed MapReduce framework, Hadoop has been widely adopted in big data processing, in which HDFS (Hadoop Distributed File System) is mostly used for data storage. Though the single master architecture of HDFS simplifies the design and implementation, it suffers from issues such as SPOF (Single Point Of Failure) and scalability, which further may become performance bottleneck. To address these problems, this paper proposes NM 2 H, a NoSQL based metadata management approach for HDFS. NM 2 H separates t… Show more
