Hadoop systems [1], sometimes called Map Reduce, can coexist with the Teradata Data Warehouse allowing each subsystem to be used for its core strength when solving business problems. Integrating the Teradata Database with Hadoop turns out to be straight forward using existing Teradata utilities and SQL capabilities. There are a few options for directly integrating data from a Hadoop Distributed File System (HDFS) with a Teradata Enterprise Data Warehouse (EDW), including using SQL and Fastload. This document focuses on using a Table Function UDF to both access and load HDFS data into the Teradata EDW. In our examples, there is historical data already in Teradata EDW, presumably derived from HDFS for trend analysis. We will show examples where the Table Function UDF approach is used to perform inserts or joins from HDFS with the data warehouse.
