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.

Developing the package

SQL Server Data Tools (SSDT) is the integrated development environment available from Microsoft to design, deploy, and develop SSIS packages. SSDT is installed when you choose to install SQL Server Client tools and Workstation Components from your SQL Server installation media. SSDT supports creation of Integration Services, Analysis Services, and Reporting Services projects. Here, we will focus on Integration Services project type.

Creating the project

Perform the following steps for creating a new project.

  1. Launch SQL Server Data Tools from SQL Server 2012 program folders as shown in the following screenshot:

  2. Create a new Project and choose Integration Services Project in the New Project dialog as shown in the following screenshot:

  3. This should create the SSIS project with a blank Package.dtsx inside it visible in the Solution Explorer window of the project as shown in the following screenshot:

Creating the Data Flow

A Data Flow is a SSIS package component, which consists...
