Hadoop Data Warehousing with Hive

There are a few setup steps I need you to do in advance. They should take a few minutes at most. You’ll find the instructions here: http://thinkbig-academy.s3.amazonaws.com/Strata2013/HiveTutorial/index.html

See you in Santa Clara! Dean Wampler

In this hands-on tutorial, you’ll learn how to use Hive for Hadoop-based data warehousing. You’ll also learn some tricks of the trade and how to handle known issues.

Writing Hive Queries

We’ll spend most of the tutorial using a series of hands-on exercises with actual Hive queries, so you can learn by doing. We’ll go over all the main features of Hive’s query language, HiveQL, and how Hive works with data in Hadoop.

Advanced Techniques

Hive is very flexible about the formats of data files, the “schema” of records and so forth. We’ll discuss options for customizing these and other aspects of your Hive and data cluster setup. We’ll briefly examine how you can write Java user defined functions (UDFs) and other plugins that extend Hive for data formats that aren’t supported natively.

Hive in the Hadoop Ecosystem

We’ll learn Hive’s place in the Hadoop ecosystem, such as how it compares to other available tools. We’ll discuss installation and configuration issues that ensure the best performance and ease of use in a real production cluster. In particular, we’ll discuss how to create Hive’s separate “metadata” store in a traditional relational database, such as MySQL. We’ll offer tips on data formats and layouts that improve performance in various scenarios.
