Abstract
So far in this book, we have explored how to develop MapReduce programs using Java. Chapter 10 introduced Hive, the SQL engine on top of the HDFS. You learned how the Hive compiler converts high–level SQL commands into MapReduce programs, which avoids having to write low–level Java programs; you can instead focus on high–level business requirements. Hive is suitable for BI developers who want to treat the HDFS as a data warehouse.
