Release Date: 2013-11-18
Building distributed applications is difficult enough without having to coordinate the actions that make them work. This practical guide shows how Apache ZooKeeper helps you manage distributed systems, so you can focus mainly on application logic. Even with ZooKeeper, implementing coordination tasks is not trivial, but this book provides good practices to give you a head start, and points out caveats that developers and administrators alike need to watch for along the way. In three separate sections, ZooKeeper contributors Flavio Junqueira and Benjamin Reed introduce the principles of distributed systems, provide ZooKeeper programming techniques, and include the information you need to administer this service. Learn how ZooKeeper solves common coordination tasks Explore the ZooKeeper API’s Java and C implementations and how they differ Use methods to track and react to ZooKeeper state changes Handle failures of the network, application processes, and ZooKeeper itself Learn about ZooKeeper’s trickier aspects dealing with concurrency, ordering, and configuration Use the Curator high-level interface for connection management Become familiar with ZooKeeper internals and administration tools
The Zookeeper's Wife: A War Story
Author: Diane Ackerman

Publisher: W. W. Norton & Company
Release Date: 2008-09-17
The New York Times bestseller now a major motion picture starring Jessica Chastain. A true story in which the keepers of the Warsaw Zoo saved hundreds of people from Nazi hands. Jan and Antonina Zabinski were Polish Christian zookeepers horrified by Nazi racism, who managed to save over three hundred people. Yet their story has fallen between the seams of history. Drawing on Antonina’s diary and other historical sources, best-selling naturalist Diane Ackerman vividly re-creates Antonina’s life as “the zookeeper’s wife,” responsible for her own family, the zoo animals, and their “Guests”—Resistance activists and refugee Jews, many of whom Jan had smuggled from the Warsaw Ghetto. Ironically, the empty zoo cages helped to hide scores of doomed people, who were code-named after the animals whose names they occupied. Others hid in the nooks and crannies of the house itself. Jan led a cell of saboteurs, and the Zabinskis’ young son risked his life carrying food to the Guests, while also tending an eccentric array of creatures in the house. With hidden people having animal names, and pet animals having human names, it’s small wonder the zoo’s codename became “The House Under a Crazy Star.” Yet there is more to this story than a colorful cast. With her exquisite sensitivity to the natural world, Diane Ackerman explores the role of nature in both kindness and savagery, and she unravels the fascinating and disturbing obsession at the core of Nazism: both a worship of nature and its violation, as humans sought to control the genome of the entire planet.
Hadoop: The Definitive Guide
Hadoop: The Definitive Guide helps you harness the power of your data. Ideal for processing large datasets, the Apache Hadoop framework is an open source implementation of the MapReduce algorithm on which Google built its empire. This comprehensive resource demonstrates how to use Hadoop to build reliable, scalable, distributed systems: programmers will find details for analyzing large datasets, and administrators will learn how to set up and run Hadoop clusters. Complete with case studies that illustrate how Hadoop solves specific problems, this book helps you: Use the Hadoop Distributed File System (HDFS) for storing large datasets, and run distributed computations over those datasets using MapReduce Become familiar with Hadoop's data and I/O building blocks for compression, data integrity, serialization, and persistence Discover common pitfalls and advanced features for writing real-world MapReduce programs Design, build, and administer a dedicated Hadoop cluster, or run Hadoop in the cloud Use Pig, a high-level query language for large-scale data processing Take advantage of HBase, Hadoop's database for structured and semi-structured data Learn ZooKeeper, a toolkit of coordination primitives for building distributed systems If you have lots of data -- whether it's gigabytes or petabytes -- Hadoop is the perfect solution. Hadoop: The Definitive Guide is the most thorough book available on the subject. "Now you have the opportunity to learn about Hadoop from a master-not only of the technology, but also of common sense and plain talk."-- Doug Cutting, Hadoop Founder, Yahoo!
