= Welcome to Sqoop

Apache Sqoop is a tool designed for efficiently transferring bulk data between Apache Hadoop and structured datastores such as relational databases. You can use Sqoop to import data from external structured datastores 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.

== Documentation

Sqoop ships with documentation, please check module “docs” for additional materials.

More documentation is available online on Sqoop home page:

== Compiling Sqoop

Sqoop uses the Maven build system, and it can be compiled and built running the following commands:

mvn compile # Compile project mvn package # Build source artifact mvn package -Pbinary # Build binary artifact

Sqoop is using Sphinx plugin to generate documentation that have higher memory requirements that might not fit into default maven configuration. You might need to increase maximal memory allowance to successfully execute package goal. This can done using following command:

export MAVEN_OPTS=“-Xmx512m -XX:MaxPermSize=512m”

Sqoop currently supports multiple Hadoop distributions. In order to compile Sqoop against a specific Hadoop version, please specify the hadoop.profile property in Maven commands. For example:

mvn package -Pbinary -Dhadoop.profile=100

Please refer to the Sqoop documentation for a full list of supported Hadoop distributions and values of the hadoop.profile property.
