| Introduction |
| ------------ |
| |
| Sqoop is a tool designed to help users of large data import |
| existing relational databases into their Hadoop clusters. Sqoop uses |
| JDBC to connect to a database, examine each table's schema, and |
| auto-generate the necessary classes to import data into HDFS. It |
| then instantiates a MapReduce job to read tables from the database |
| via the DBInputFormat (JDBC-based InputFormat). Tables are read |
| into a set of files loaded into HDFS. Both SequenceFile and |
| text-based targets are supported. Sqoop also supports high-performance |
| imports from select databases including MySQL. |
| |
| This document describes how to get started using Sqoop to import |
| your data into Hadoop. |
