cloudera的cdh是一個方便的工具，其中的hue號稱是hadoop UI，提供了強大的圖形操作界面，是一個非常好用的工具。下面介紹如何配置jdbc來進行數據的采集。

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/
