This article will explain how to use Arm Treasure Data with Pentaho Data Integration by using our JDBC driver. By combining Treasure Data with Pentaho, users can scale their existing Pentaho Data Integration environment to handle huge volumes of data.
- Basic knowledge of Treasure Data. The Quickstart Guide is a good place to start.

Download Pentaho Data Integration (Kettle)
You can download Pentaho Data Integration (Kettle) from the link below. Version 4.3.0 was tested for this article
Download JDBC Driver
You can download the driver from the link below. The driver is still in beta, so any feedback would be appreciated.
|This driver works only with Treasure Data. It does not work with other environments such as your local Hadoop/Hive cluster.|
Copy JDBC Driver Jar to Pentaho Data Integration
Before starting Pentaho Data Integration, please copy the Treasure Data JDBC driver to the
libext/JDBC directory specified by Pentaho Data Integration.
$ cp td-jdbc-VERSION.jar \ <pentaho-data-integration-install>/data-integration/libext/JDBC/
Create Treasure Data Database Connection
Let’s add Treasure Data as Pentaho Data Integration’s database connection and make a new transformation. Please follow the procedure below.
Step 1: Create a New Transform
Transforms as shown in the figure below. To create a new transform, right-click
New in the context menu.
Step 2: Create New Database Connection
Tools > Wizard > Create database connection... will bring up a pop-up window to create a new database connection. Select the database name and type as shown below.
Step 3: Specify the Driver Class Name
Specify the connection’s URL and name of the driver class as shown below.
Step 4: Set the Username and Password
Specify your username and password as shown below. Please use your Treasure Data credentials for these fields (Your User Name is the email address used to register on Treasure Data). Press the
Finish button to create the database connection on your Pentaho Data Integration environment.
Use Treasure Data Database as Table input
Step 1: Specify Table Input
Table input from the transform’s
Input context menu. Drag and drop onto the workspace as shown below.
Step 2: Edit the Table Input
Table input icon on the workspace. Select
Edit step from the context menu. Configure your Table input as shown below.
We cover the query above in the JasperSoft iReport with JDBC Driver article.
Step 3: Confirm the Table Input
To confirm the behavior of the Table input, write out your data on Treasure Data to JSON output as shown below.
Tips: How can I use Pentaho through a proxy?
Check ‘start-pentaho.bat’ or ‘start-pentaho.sh’, and add the following parameters to CATALINA_OPTS option:
CATALINA_OPTS="-Dhttp.proxyHost=<proxy address> -Dhttp.proxyPort=<proxy port>"
