Hadoop has changed the way large data sets are analyzed, stored, transferred, and processed. At such low cost, it provides benefits like supports partial failure, fault tolerance, consistency, scalability, flexible schema, and so on. It also supports cloud computing. More and more number of individuals are looking forward to mastering their Hadoop skills. While initiating with Hadoop, most users are unsure about how to proceed with Hadoop. They are not aware of what are the pre-requisite or data structure they should be familiar with. Or How to make the most efficient use of Hadoop and its ecosystem. To help them with all these queries and other issues this e-book is designed. The book gives insights into many of Hadoop libraries and packages that are not known to many Big data Analysts and Architects.

This book comprehensively covers the principles of Risk-based vulnerability management (RBVM) – one of the most challenging tasks in cybersecurity -- from the foundational mathematical models to building your own decision engine to identify, mitigate, and eventually forecast the vulnerabilities that pose the greatest threat to your organization. You will learn: how to structure data pipelines in security and derive and measure value from them; where to procure open-source data to better your organization’s pipeline and how to structure it; how to build a predictive model using vulnerability data; how to measure the return on investment a model in security can yield; which organizational structures and policies work best, and how to use Data Science to detect when they are not working in security; and ways to manage organizational change around Data Science implementation. Using the many sources of data we have and the mathematical modeling we use to compensate for mathematical scale, randomness, and uncertainty, Machine Learning (ML) offers a quick and efficient way to better prioritize decisions and remediate the vulnerabilities that pose the greatest risk. ML is a classification of Artificial Intelligence in which algorithms automatically improve over time by observing patterns in data and applying those patterns to subsequent actions.

Data lakes and warehouses have become increasingly fragile, costly, and difficult to maintain as data gets bigger and moves faster. Data meshes can help your organization decentralize data, giving ownership back to the engineers who produced it. This book provides a concise yet comprehensive overview of data mesh patterns for streaming and real-time data services. Data mesh is one of the most popular architectures for data platforms that many are exploring today. This book will help you get a full understanding of this self-servicing data platform in a streaming context. Today, batch processing dominates all extract, transform, and load (ETL) processes in most businesses. This book will help show a different perspective of data pipelines and apply the same concepts you already understand in batch ETL, but in a streaming ETL in the context of a data mesh. This book is designed to help you understand the essential concepts around streaming data mesh—the concepts, architectures, and technologies at its core.

This book provides alternative approach to get started with Big Data Query using Apache Impala. This book describes how to work with Apache Impala and to perform queries inside Apache Impala. Apache Impala is a modern, open source, distributed SQL query engine for Apache Hadoop. With Impala, we can query data, whether stored in HDFS, Apache Hive or Apache HBase – including SELECT, JOIN, and aggregate functions. You can find the official project on this link, In this book, we learn how to perform queries on Apache Impala. Apache Hue is a web tool that can be used to perform queries on Apache Impala. We can say Apache Hue like MySQL Workbench in MySQL or SQL Server Management Studio in SQL Server. We can use Apache Hue to write queries to Apache Impala easily. In this chapter, we learn how to access Apache Impala from a program. We will use Java application for a sample of client application. To access Apache Impala, we can use ODCB and JDBC drivers from Cloudera. We will JDBC 4.2 driver for Java application. Next, we create Java application project.

Many real-life systems are dynamic, evolving, and intertwined. Examples of such systems displaying 'complexity', can be found in a wide variety of contexts ranging from economics to biology, to the environmental and physical sciences. The study of complex systems involves analysis and interpretation of vast quantities of data, which necessitates the application of many classical and modern tools and techniques from statistics, network science, Machine Learning, and agent-based modelling. Drawing from the latest research, this self-contained and pedagogical text describes some of the most important and widely used methods, emphasising both empirical and theoretical approaches. More broadly, this book provides an accessible guide to a data-driven toolkit for scientists, engineers, and social scientists who require effective analysis of large quantities of data, whether that be related to social networks, financial markets, economies or other types of complex systems.

This book is designed to equip students to navigate through MS Excel and basic data computation methods, which are essential tools in research or professional settings and in classrooms. It illustrates the concepts used in research and data analysis and economic and financial decision-making in business and in daily life. The book will help students acquire knowledge and develop skills in statistical techniques and financial analysis using MS Excel. The book is developed through three phases, with each phase standing on its own as well as providing a foundation for the next. In the first phase, Excel is introduced for the students to learn entry of data, manipulation of data, carrying out operations and develop presentations. The second phase introduces basic statistical measures of data summarisation and analysis, following which these are illustrated in Excel spreadsheets with the techniques introduced in the first phase. In addition, a few advanced tools of statistical analysis are introduced and illustrated in Excel. The third phase introduces financial measures of common use, their general computation and working them out in Excel.

Linux is an open-source operating system whereas Windows OS is commercial. Linux has access to source code and alters the code as per user need whereas Windows does not have access to the source code. In Linux, the user has access to the source code of the kernel and alters the code according to his need. Currently, more than 300 Linux distributions are actively maintained. There are commercially backed distributions, such as Fedora (Red Hat), openSUSE (SUSE), and Ubuntu (Canonical Ltd.), and entirely community-driven distributions, such as Debian, Slackware, Gentoo, and Arch Linux. Linux is not hard to learn. The more experience you have using modern technology, the easier you'll find it to master the basics of Linux. You can learn the basic Linux commands in a few days but it will likely take a few weeks to become more familiar with these commands. This Book covers All Basic Linux knowledge, Commands, and Free Cheatsheets which is very good for Beginners.
