Practical Issues using Distributed Computing Environments – Apache Hadoop

摘要

The paper presents practical results obtained with sequential standard programming, RPC/RMI mechanism and Apache Hadoop distributed computing platform for a problem of computation time and power that might be used in e-mail text searching. First section is about Distributed Computing technologies and middleware introduction. In second and third section are shown few details about RPC/RMI and Apache Hadoop approaches. The fourth section presents the results of the computation for a classic problem such as word counting from large text files using standard versus remote procedure call versus map-reducing approach. In the end are shown the main advantages of the distributed systems and computing environments.
