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.
