Today enterprises generate huge volumes of data. In order to provide effective services and to make smarter and more intelligent decisions from these huge volumes of data, enterprises use big-data analytics. In recent years, Hadoop has been used for massive data storage and efficient distributed processing of data. The Yet Another Resource Negotiator (YARN) framework solves the design problems related to resource management faced by the Hadoop 1.x framework by providing a more scalable, efficient, flexible, and highly available resource management framework for distributed data processing.This book starts with an overview of the YARN features and explains how YARN provides a business solution for growing big data needs. You will learn to provision and manage single, as well as multi-node, Hadoop-YARN clusters in the easiest way. You will walk through the YARN administration, life cycle management, application execution, REST APIs, schedulers, security framework and so on. You will gain insights about the YARN components and features such as ResourceManager, NodeManager, ApplicationMaster, Container, Timeline Server, High Availability, Resource Localisation and so on.The book explains Hadoop-YARN commands and the configurations of components and explores topics such as High Availability, Resource Localization and Log aggregation. You will then be ready to develop your own ApplicationMaster and execute it over a Hadoop-YARN cluster.Towards the end of the book, you will learn about the security architecture and integration of YARN with big data technologies like Spark and Storm. This book promises conceptual as well as practical knowledge of resource management using YARN.

Learning Zig. A reimagined introduction to low-level programming with Zig
Alex Rios
System programming has long forced developers to choose between safety and performance, but Zig changes the game with its no hidden control flow philosophy and explicit resource management. If you've struggled with memory leaks, undefined behavior, or cryptic compiler errors, Zig offers an alternative that puts you back in control.Alex Rios, a seasoned software engineer with experience building high-throughput systems across fintech, telecom, and gaming industries, brings his unconventional system design approach and offers insight into Zig, as someone who's seen the limitations of existing languages firsthand.You’ll get to grips with Zig's safety-centric design fundamentals, which will guide you through setting up your app development environment and writing your first programs. You'll then explore Zig's distinctive features in depth, such as explicit error handling, manual memory management, and compile-time execution. The book tackles each topic with a blend of technical depth and wit, ensuring you grasp not just the how but also the why behind Zig's design decisions.By the end of this book, you'll be ready to build a complete application that interacts with the OS, third-party libraries, and C dependencies, as well as engage with Zig's growing community and contribute to its ecosystem.

Least Privilege Security is the practice of assigning users and programs the minimum permissions required to complete a given task. Implementing this principle in different versions of Microsoft Windows requires careful planning and a good understanding of Windows security. While there are benefits in implementing Least Privilege Security on the desktop, there are many technical challenges that you will face when restricting privileges.This book contains detailed step-by-step instructions for implementing Least Privilege Security on the desktop for different versions of Windows and related management technologies. It will provide you with quick solutions for common technical challenges, Microsoft best practice advice, and techniques for managing Least Privilege on the desktop along with details on the impact of Least Privilege Security.The book begins by showing you how to apply Least Privilege Security to different categories of users. You will then prepare a desktop image with Least Privilege Security enabled from the start and deploy the new image while preserving users' files and settings. You will identify problems with applications caused by Least Privilege Security using the Application Compatibility Toolkit. This book will help you configure User Account Control on multiple computers using Group Policy and support Least Privilege user accounts using reliable remote access. Then, you will modify legacy applications for Least Privilege Security, achieving the best balance between compatibility and security by using Application Compatibility shims. You will install per-machine ActiveX Controls using the ActiveX Installer Service (AxIS). The book will help you implement best practices for working with ActiveX Controls in a managed environment. Finally, you will deploy default Software Restriction Policy (SRP) or AppLocker rules to ensure only programs installed in protected locations can run and blacklist applications using SRP or AppLocker.
