This document discusses Sqoop, a tool for importing structured data from databases into Hadoop. Sqoop automates the process of importing data from relational databases into HDFS and generating code to work with the imported data. It supports importing from popular databases into various data formats like text files or SequenceFiles. Sqoop also integrates with Hive, allowing SQL-like queries over imported data. The tool aims to simplify common ETL tasks and make database data accessible for MapReduce jobs and analytics on Hadoop.
