Описание: Honestly, there are a lot of Hive books already in the market. Why another one on same topic? Here's why. I read through most if not all of the existing Hive Books in writing this book. The problem with them is that they were written as an add-on chapter to an already big and complex Hadoop or BigData book. Very few were dedicated to Hive and Hive only. Very few had the mindset of a practical programmer, needing hand-on examples. Very few cut through the noise to deliver practical tips for beginners and pro's alike who want to work with Hive.
Haven struggled in the early days of learning have, I decided to synthesize my notes and lessons learned into this manual.
This example-driven guide shows you how to work with Hive.
It contains proven steps and strategies on how to become a truly savvy Hive Programmer.
If you are already familiar with SQL then you may well be thinking about how to add Hadoop skills to your tool belt as an option for data processing.
From a querying perspective, using Apache Hive is the next logical step you can take. Using Hive provides a familiar interface to data held in a Hadoop cluster and is a great way to get started with minimal learning curve.
Apache Hive a is data warehouse infrastructure built on top of Apache Hadoop for providing data summarization, ad-hoc query, and analysis of large datasets. It provides a mechanism to project structure onto the data in Hadoop and to query that data using a SQL-like language called Hive Query Language (HiveQL or HQL).
In this book, I will take you deep down into Hive. I will do what many other books haven't successfully done. Provide you with High level information about Apache Hive that will allow you to strategically shine in that next board room presentation, while leaving you with enough details to tactically take on BigData projects and amaze your peers in the process.
The next step is to get a notebook and begin brainstorming on all sections in relation to the tips included.
