based on the business requirement – supports linear scale-out – has capability for rapid deployment – supports variety of data formats – provides data analysis and reporting tools – provides real-time data analysis software – has tools for searching the data through large data sets Hadoop ● http://hadoop.apache.org/ ● an open-source software framework for storing data and running applications on clusters of commodity hardware ● why it is so important? – ability to store and process huge amounts of any kind of data, quickly – computing power - Hadoop's distributed computing model processes big data fast ● the more computing nodes you use, the more processing power you have – fault tolerance - data and application processing are protected against hardware failure ● if a node goes down, jobs are automatically redirected to other nodes to make sure the distributed computing does not fail ● multiple copies of all data are stored automatically. – flexibility - unlike traditional relational databases, you don’t have to preprocess data before storing it – low cost - the open-source framework is free and uses commodity hardware to store large quantities of data – scalability - you can easily grow your system to handle more data simply by adding nodes with little administration effort Hadoop Source: https://www.sas.com/en_us/insights/big-data/hadoop.html Hadoop ● challenges: – MapReduce programming is not a good match for all problems ● good for simple information requests and problems that can be divided into independent units ● not efficient for iterative and interactive analytic tasks – a widely acknowledged talent gap - it can be difficult to find entry-level programmers who have sufficient Java skills to be productive with MapReduce ● distribution providers are racing to put relational (SQL) technology on top of Hadoop ● Hadoop administration seems part art and part science, requiring low-level knowledge of operating systems, hardware and Hadoop kernel settings – data security issues ● Kerberos authentication protocol is a great step toward making Hadoop environments secure – lacking tools for data quality and standardization Hadoop ● important application domains: – Digital Marketing Optimization – Data exploration and discovery (Product and sales data for online shopping portal and stores) – Fraud detection and prevention – Social network

  • HPCC Benchmarking
    Final Project Report HPCC Benchmarking MAY 29, 2018 RUSHIKESH GHATPANDE SUPERVISOR :VINCENT WFREEH COMPUTER SCIENCE DEPARTMENT NC STATE UNIVERSITY ABSTRACT igh-performance Computing Cluster (HPCC) Thor is a big data analytics engine. It is designed to execute big data workflows including extraction, loading, cleansing, trans- Hformations, linking, and indexing. A Thor cluster is similar in its function, execution environment, filesystem, and capabilities to the Google and Hadoop MapReduce platforms. It can be optimized for its parallel data processing purpose. HPCC’s declarative and data flow-oriented language - ECL defines the processing result desired; the specific processing steps required to perform the processing are left to the language compiler. These salient features make it a viable alternative to established big data analytics engines like Spark and Hadoop. In this report, we have benchmarked HPCC alongside Hadoop. We present a detailed study of scalability, time for execution, and system-level metrics like CPU utilization, memory utilization and disk I/O patterns. We try to identify general trends in performance and which engine is better suited for a particular workload. i TABLE OF CONTENTS Page List of Tables iv List of Figures v 1 Introduction 1 2 Requirements 3 2.1 Functional Requirements .................................. 3 2.2 Non-Functional Requirements ............................... 3 3 System Environment5 3.1 Hardware Specifications................................... 5 3.2 Software Specifications.................................... 5 4 Design, Implementation and Results7 4.1 Design.............................................. 7 4.2 Implementation ........................................ 8 4.3 Results ............................................. 9 5 Observations and Challenges 13 5.1 Observation........................................... 13 5.1.1 CPU Utilization.................................... 13 5.1.2 Code Optimization.................................. 15 5.2 Challenges ..........................................

  • Beyond Batch Processing: Towards Real-Time and Streaming Big Data
    Beyond Batch Processing: Towards Real-Time and Streaming Big Data Saeed Shahrivari, and Saeed Jalili Computer Engineering Department, Tarbiat Modares University (TMU), Tehran, Iran [email protected], [email protected] Abstract: Today, big data is generated from many sources and there is a huge demand for storing, managing, processing, and querying on big data. The MapReduce model and its counterpart open source implementation Hadoop, has proven itself as the de facto solution to big data processing. Hadoop is inherently designed for batch and high throughput processing jobs. Although Hadoop is very suitable for batch jobs but there is an increasing demand for non-batch processes on big data like: interactive jobs, real-time queries, and big data streams. Since Hadoop is not proper for these non-batch workloads, new solutions are proposed to these new challenges. In this article, we discuss two categories of these solutions: real-time processing, and stream processing for big data. For each category, we discuss paradigms, strengths and differences to Hadoop. We also introduce some practical systems and frameworks for each category. Finally, some simple experiments are done to show effectiveness of some solutions compared to available Hadoop-based solutions. Keywords: Big data, MapReduce, Real-time processing, Stream processing 1. Introduction The “Big Data” paradigm is getting an expanding popularity recently. The “Big Data” term is generally used for datasets which are so huge that cannot be processed and managed using classical solutions like Relational Data Base Systems (RDBMS). Besides volume, large velocity and variety are other challenges of big data. Numerous sources generate big data.

As you're writing a program you may think "I wish ECL had such-and-such an operator”. So you go and write it. Afterward you realize that using the new operator would simplify the design of another part of the program, and so on. Language and program evolve together. Like the border between two warring states, the boundary between language and program is drawn and redrawn, until eventually it comes to rest along the mountains and rivers, the natural frontiers of your problem.

  • HPCC Systems: Introduction to HPCC (High-Performance Computing Cluster)
    White Paper HPCC Systems: Introduction to HPCC (High-Performance Computing Cluster) Author: Anthony M. Middleton, Ph.D. LexisNexis Risk Solutions Date: May 24, 2011 Executive Summary As a result of the continuing information explosion, many organizations now have the need to process and analyze massive volumes of data. These data-intensive computing requirements can be addressed by scalable systems based on hardware clusters of commodity servers coupled with system software to provide a distributed file storage system, job execution environment, online query capability, parallel application processing, and parallel programming development tools. The LexisNexis HPCC platform provides all of these capabilities in an integrated, easy to implement and use, commercially-available high-performance computing environment. This paper provides an introduction to the LexisNexis HPCC system architecture also referred to (in the government space) as the LexisNexis Data Analytics Supercomputer (DAS). LexisNexis Risk Solutions, an industry leader in data content, data aggregation, and information services, independently developed and implemented the HPCC platform as a solution for its own data-intensive computing requirements. In a similar manner to Hadoop (the open source implementation of MapReduce), the LexisNexis approach also uses commodity clusters of hardware running the Linux operating system and includes additional system software and middleware components to provide a complete and comprehensive job execution environment and distributed query and filesystem support needed for data-intensive computing. The HPCC platform includes a powerful high-level, heavily-optimized, data-centric declarative language for parallel data processing called ECL (Enterprise Data Control Language) which is also described in this paper. The power, flexibility, advanced capabilities, speed of development, maturity, and ease of use of the ECL programming language is a primary distinguishing factor between the LexisNexis HPCC platform and other data-intensive computing solutions.
