Integrate HPCC Systems Data in the Pentaho Report Designer

Publish reports based on HPCC Systems data in the Pentaho BI tool.

The CData JDBC Driver for HPCC Systems data enables access to live data from dashboards and reports. This article shows how to connect to HPCC Systems data as a JDBC data source and publish reports based on HPCC Systems data in Pentaho.

Connect and Create a Report

  1. Copy the JAR file of the driver, located in the lib subfolder of the installation directory, to the \Report-Designer\lib\jdbc\ folder in the Pentaho directory.
  2. Run the report-designer.bat file in the \Report-Designer\ folder to open the Report-Designer UI.
  3. Create a new data source with the driver by clicking Data -> Add Data Source -> Advanced -> JDBC (Custom) and then creating a new HPCC Systems connection. In the resulting dialog, configure the connection properties as shown below.

    • Custom Connection URL property: Enter the JDBC URL. This starts with jdbc:hpcc: and is followed by a semicolon-separated list of connection properties.

      To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

      Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

      Set Cluster to the target cluster.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the HPCC Systems JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.hpcc.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

      Below is a typical JDBC URL:

      jdbc:hpcc:URL=http://127.0.0.1:8510;User=test;password=xA123456;Version=1;Cluster=hthor;
    • Custom Driver Class Name: Enter cdata.jdbc.hpcc.HPCCDriver.
    • User Name: The username to authenticate with.
    • Password: The password to authenticate with.

Add HPCC Systems Data to a Report

You are now ready to create a report with HPCC Systems data.

  1. Add the HPCC Systems source to your report: Click Data -> Add Data Source -> JDBC and select the data source.

  2. Configure the query. This article uses the one below:

    SELECT SUM(hpcc::test::orders.Price), hpcc::test::customers.CustomerName FROM hpcc::test::orders INNER JOIN hpcc::test::customers ON hpcc::test::orders.CustomerId=hpcc::test::customers.CustomerId;GROUP BY hpcc::test::customers.CustomerName
  3. Drag a chart onto your report and double-click it to edit the chart. Run the report to display the chart. You can use the results of this query to create a simple chart for the hpcc::test::orders table.
  4. Finally, run the report to see the chart.
