Definition - What does Apache Sqoop mean?
Techopedia explains Apache Sqoop
Sqoop, an integral part of Hadoop, can perform this transfer in an automated fashion. Moreover, the data imported into Hadoop can be transformed with MapReduce before exporting them back to the RDBMS. Sqoop can also generate Java classes for programmatically interacting with imported data.
Sqoop uses a connector-based architecture that allows it to use plugins for connecting with external databases.
