Microsoft SQL Server 2012 with Hadoop

Overview of this book

With the explosion of data, the open source Apache Hadoop ecosystem is gaining traction, thanks to its huge ecosystem that has arisen around the core functionalities of its distributed file system (HDFS) and Map Reduce. As of today, being able to have SQL Server talking to Hadoop has become increasingly important because the two are indeed complementary. While petabytes of unstructured data can be stored in Hadoop taking hours to be queried, terabytes of structured data can be stored in SQL Server 2012 and queried in seconds. This leads to the need to transfer and integrate data between Hadoop and SQL Server. Microsoft SQL Server 2012 with Hadoop is aimed at SQL Server developers. It will quickly show you how to get Hadoop activated on SQL Server 2012 (it ships with this version). Once this is done, the book will focus on how to manage big data with Hadoop and use Hadoop Hive to query the data. It will also cover topics such as using in-memory functions by SQL Server and using tools for BI with big data. Microsoft SQL Server 2012 with Hadoop focuses on data integration techniques between relational (SQL Server 2012) and non-relational (Hadoop) worlds. It will walk you through different tools for the bi-directional movement of data with practical examples. You will learn to use open source connectors like SQOOP to import and export data between SQL Server 2012 and Hadoop, and to work with leading in-memory BI tools to create ETL solutions using the Hive ODBC driver for developing your data movement projects. Finally, this book will give you a glimpse of the present day self-service BI tools such as Excel and PowerView to consume Hadoop data and provide powerful insights on the data.

Chapter 2. Using Sqoop – The SQL Server Hadoop Connector

Sqoop is an open source Apache project, which facilitates data exchange between Hadoop and any traditional Relational Database Management System (RDBMS). It uses the MapReduce framework under the hood to perform the import/export operations and often is a common choice for integrating data from relational and non-relational data stores.

Microsoft SQL Server Connector for Apache Hadoop (SQL Server-Hadoop Connector) is a Sqoop-based connector that is specifically designed for efficient data transfer between SQL Server and Hadoop. This connector is optimized for bulk transfer of the data bi-directionally, it does not support extensive formatting or transformation on the data while being imported or exported on the fly. After reading this chapter, you will be able to:

  • Install and configure the Sqoop connector

  • Import data from SQL Server to Hadoop

  • Export data from Hadoop to SQL Server
