Abstract
Chapter 2 showed us how to use PolyBase to integrate SQL Server with Azure Blob Storage. In this chapter, we will integrate to the original external data source: Hadoop. In the first part of this chapter, we will take a peek at an already-built Hadoop cluster. Then, we will configure PolyBase to work with the two key variants of Hadoop (pending the release of an on-premises version of Cloudera Data Platform). Next, we will review what changes in terms of PolyBase functionality between Azure Blob Storage and Hadoop. After this review, we will create the infrastructure needed to query a Hadoop external data source. Finally, we will query this external data source and confirm that data retrieval and data insertion both work as they do in Azure Blob Storage.
