  • Decentralising Big Data Processing Scott Ross Brisbane
    School of Computer Science and Engineering Faculty of Engineering The University of New South Wales Decentralising Big Data Processing by Scott Ross Brisbane Thesis submitted as a requirement for the degree of Bachelor of Engineering (Software) Submitted: October 2016 Student ID: z3459393 Supervisor: Dr. Xiwei Xu Topic ID: 3692 Decentralising Big Data Processing Scott Ross Brisbane Abstract Big data processing and analysis is becoming an increasingly important part of modern society as corporations and government organisations seek to draw insight from the vast amount of data they are storing. The traditional approach to such data processing is to use the popular Hadoop framework which uses HDFS (Hadoop Distributed File System) to store and stream data to analytics applications written in the MapReduce model. As organisations seek to share data and results with third parties, HDFS remains inadequate for such tasks in many ways. This work looks at replacing HDFS with a decentralised data store that is better suited to sharing data between organisations. The best fit for such a replacement is chosen to be the decentralised hypermedia distribution protocol IPFS (Interplanetary File System), that is built around the aim of connecting all peers in it's network with the same set of content addressed files. ii Scott Ross Brisbane Decentralising Big Data Processing Abbreviations API Application Programming Interface AWS Amazon Web Services CLI Command Line Interface DHT Distributed Hash Table DNS Domain Name System EC2 Elastic Compute Cloud FTP File Transfer Protocol HDFS Hadoop Distributed File System HPC High-Performance Computing IPFS InterPlanetary File System IPNS InterPlanetary Naming System SFTP Secure File Transfer Protocol UI User Interface iii Decentralising Big Data Processing Scott Ross Brisbane Contents 1 Introduction 1 2 Background 3 2.1 The Hadoop Distributed File System .
