Book Description

Need to move a relational database application to Hadoop? This comprehensive guide introduces you to Apache Hive, Hadoop’s data warehouse infrastructure. You’ll quickly learn how to use Hive’s SQL dialect—HiveQL—to summarize, query, and analyze large datasets stored in Hadoop’s distributed filesystem. This example-driven guide shows you how to set up and configure Hive in your environment, provides a detailed overview of Hadoop and MapReduce, and demonstrates how Hive works within the Hadoop ecosystem. You’ll also find real-world case studies that describe how companies have used Hive to solve unique problems involving petabytes of data. Use Hive to create, alter, and drop databases, tables, views, functions, and indexes Customize data formats and storage options, from files to external databases Load and extract data from tables—and use queries, grouping, filtering, joining, and other conventional query methods Gain best practices for creating user defined functions (UDFs) Learn Hive patterns you should use and anti-patterns you should avoid Integrate Hive with other data processing programs Use storage handlers for NoSQL databases and other datastores Learn the pros and cons of running Hive on Amazon’s Elastic MapReduce

Book Description

The revolutionary beekeeping method that is providing a radical return to healthy bee hives in the U.S. and around the world today is explained in detail in A Lively Hive. Author, Alex Tuchman, the director of Spikenard Farm Honeybee Sanctuary in Floyd, Virginia, walks the reader through both the philosophy and practical applications that have shown remarkable success rates. In the past five years, the catastrophic loss of 45% of U.S. honeybee colonies has been well documented. By contrast, in that same time period Spikenard Farm Honeybee Sanctuary has shown an astonishing low loss of only 12%. Tuchman shares the significant difference between beekeeping methods that exploit the honeybee for human agribusiness and alternative methods to beekeeping that are in line with the instincts and wisdom of the honeybees themselves. The amazing results, as it turns out, are found at heart in the relationship and communication between the honeybee and the human-that when we listen to what the bees are telling us, only then are we guided to best provide for the bees' needs in the physical world.
