HPCC JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with HPCC Systems!



Connect to HPCC Systems data in NetBeans with the data source configuration wizard.

The CData JDBC Driver for HPCC Systems integrates connectivity to live HPCC Systems data in IDEs that support JDBC. The JDBC standard enables you to use built-in data access wizards and other tools supporting rapid development. This article shows how to connect to HPCC Systems data in NetBeans. You will create a connection and load HPCC Systems data in the Table Editor.

Create a JDBC Data Source for HPCC Systems in NetBeans

To create the JDBC data source, expand the Database node in the Service window, right-click the Drivers node, and select New Driver. In the New Driver wizard that results, enter the following information:

  • Driver File(s): Click Add and, in the file explorer dialog that appears, select the cdata.jdbc.hpcc.jar file. The driver JAR is located in the lib subfolder of the installation directory.
  • Driver Class: Click Find to search for the driver class inside the JAR. Then select cdata.jdbc.hpcc.HPCCDriver from the menu.
  • Name: Enter the name for the driver.

Define Connection Parameters

Follow the steps below to define required connection properties:

  1. In the Service window, right-click the Database node and click New Connection.

  2. In the New Connection Wizard, enter the following connection properties:

    • Driver Name: In the menu, select the CData JDBC Driver for HPCC Systems.
    • User Name: Enter the username. This can also be defined in the JDBC URL.
    • Password: Enter the password. This can also be defined in the JDBC URL.
    • JDBC URL: Specify the JDBC URL.

      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.

      A typical JDBC URL is the following:

      jdbc:hpcc:URL=http://127.0.0.1:8510;User=test;password=xA123456;Version=1;Cluster=hthor;

Query HPCC Systems Data

To connect to HPCC Systems data, right-click the connection in the Database node and click Connect. After the connection is established, you can expand it to discover schema information.

To load a table in the Data Views window, right-click the table and then click View Data..
