Installing the JDBC Drivers
Sqoop 2 does not ship with third party JDBC drivers. You must download them separately and save them to the /var/lib/sqoop2
/ directory. The following sections show how to install the most common JDBC Drivers.
Installing the MySQL JDBC Driver
Download the MySQL JDBC driver from http://www.mysql.com/downloads/connector/j/5.1.html. You will need to sign up for an account if you don't already have one, and log in, before you can download it. Then copy it to the /var/lib/sqoop2
directory. For example:
$ sudo cp mysql-connector-java-version
/mysql-connector-java-version
-bin.jar /var/lib/sqoop2/
Note: At the time of publication, version
was 5.1.25
, but the version may have changed by the time you read this.
Installing the Oracle JDBC Driver
You can download the JDBC Driver from the Oracle website, for example http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html. You must accept the license agreement before you can download the driver. Download the ojdbc6.jar
file and copy it to /var/lib/sqoop2/
directory:
$ sudo cp ojdbc6.jar /var/lib/sqoop2/
Installing the Microsoft SQL Server JDBC Driver
Installing the PostgreSQL JDBC Driver
Download the PostgreSQL JDBC driver from http://jdbc.postgresql.org/download.html and copy it to the /var/lib/sqoop2/
directory. For example:
$ curl -L 'http://jdbc.postgresql.org/download/postgresql-9.2-1002.jdbc4.jar' -o postgresql-9.2-1002.jdbc4.jar$ sudo cp postgresql-9.2-1002.jdbc4.jar /var/lib/sqoop2/
