Configuring Sqoop 2

This section explains how to configure the Sqoop 2 server.

Configuring which Hadoop Version to Use

The Sqoop 2 client does not interact directly with Hadoop MapReduce, and so it does not require any MapReduce configuration.

The Sqoop 2 server can work with either MRv1 or YARN. It cannot work with both simultaneously.

You set the MapReduce version the Sqoop 2 server works with by means of the alternatives command (or update-alternatives, depending on your operating system):
  • To use YARN:
    alternatives --set sqoop2-tomcat-conf /etc/sqoop2/tomcat-conf.dist
  • To use MRv1:
    alternatives --set sqoop2-tomcat-conf /etc/sqoop2/tomcat-conf.mr1

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 on the server. The following sections show how to install the most common JDBC drivers. Once you have installed the JDBC drivers, restart the Sqoop 2 server so that the drivers are loaded.

Installing the MySQL JDBC Driver

Download the MySQL JDBC driver here. 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/
At the time of publication, version was 5.1.31, 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 here. 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

Download the Microsoft SQL Server JDBC driver here and copy it to the /var/lib/sqoop2/ directory. For example:

$ curl -L '' | tar xz
$ sudo cp sqljdbc_4.0/enu/sqljdbc4.jar /var/lib/sqoop2/

Installing the PostgreSQL JDBC Driver

Download the PostgreSQL JDBC driver here and copy it to the /var/lib/sqoop2/ directory. For example:

$ curl -L '' -o postgresql-9.2-1002.jdbc4.jar
$ sudo cp postgresql-9.2-1002.jdbc4.jar /var/lib/sqoop2/
