Sqoop

Sqoop is an Apache Foundation project whose goal is to improve the cohabitation of traditional DBMS type systems with the Hadoop platform.

It allows data to be exported from the database and normally costly processing to be performed using the Hadoop cluster. Data collection systems working with databases are the most common today. In this way, data can be collected from traditional applications that are unable to connect to the cluster.
Conversely, processing results can be exported to a third party database for exploitation by an application (e.g. for reporting purposes).
Sqoop was designed with the primary objective of providing high performance levels in mass import and export operations.
