Create a JDBC Data Source for Impala Data

Follow the steps below to load the driver JAR in DBeaver.

  1. Open the DBeaver application and, in the Databases menu, select the Driver Manager option. Click New to open the Create New Driver form.
  2. In the Driver Name box, enter a user-friendly name for the driver.
  3. To add the .jar, click Add File.
  4. In the create new driver dialog that appears, select the cdata.jdbc.apacheimpala.jar file, located in the lib subfolder of the installation directory.
  5. Click the Find Class button and select the ApacheImpalaDriver class from the results. This will automatically fill the Class Name field at the top of the form. The class name for the driver is cdata.jdbc.apacheimpala.ApacheImpalaDriver.
  6. Add jdbc:apacheimpala: in the URL Template field.

Create a Connection to Impala Data

Follow the steps below to add credentials and other required connection properties.

  1. In the Databases menu, click New Connection.
  2. In the Create new connection wizard that results, select the driver.
  3. On the next page of the wizard, click the driver properties tab.

  4. Enter values for authentication credentials and other properties required to connect to Impala.

    In order to connect to Apache Impala, set the Server, Port, and ProtocolVersion. You may optionally specify a default Database. To connect using alternative methods, such as NOSASL, LDAP, or Kerberos, refer to the online Help documentation.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.apacheimpala.jar

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

    Below is a typical connection string:

    jdbc:apacheimpala:Server=127.0.0.1;Port=21050;
