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.
- 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
In earlier releases, the mechanism for setting the MapReduce version was the CATALINA_BASEvariable in the /etc/defaults/sqoop2-server file. This does not work as of CDH 5 Beta 2, and in fact could cause problems. Check your /etc/defaults/sqoop2-server file and make sure CATALINA_BASE is not set.
Installing the JDBC Drivers
The JDBC drivers need to be installed only on the machine where Sqoop is executed; you do not need to install them on all nodes in your Hadoop cluster.
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.
Make sure you have at least version 5.1.31. Some systems ship with an earlier version that may not work correctly with Sqoop.
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 'http://download.microsoft.com/download/0/2/A/02AAE597-3865-456C-AE7F-613F99F850A8/sqljdbc_4.0.2206.100_enu.tar.gz' | 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 '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/
