Apache Sqoop stands for "SQL-to-Hadoop" which is a tool designed for efficiently transferring the bulk of data between Apache Hadoop systems and structured datastores systems such as relational databases. Sqoop can be used to import data from external structured databases into Hadoop Distributed File System or related systems like Hive and HBase. Conversely, Sqoop can be used to extract data from Hadoop and export it to external structured datastores such as relational databases and enterprise data warehouses systems. Sqoop uses MapReduce to perform import and export operations.
