Manage Impala data with visual tools in DBeaver like the query browser.
The CData JDBC Driver for Impala implements JDBC standards that enable third-party tools to interoperate, from wizards in IDEs to business intelligence tools. This article shows how to connect to Impala data with wizards in DBeaver and browse data in the DBeaver GUI.
Create a JDBC Data Source for Impala Data
Follow the steps below to load the driver JAR in DBeaver.
- Open the DBeaver application and, in the "Database" menu, select the "Driver Manager" option. Click "New" to open the "Create new driver" form.
- In the Settings tab:
- Set Driver Name to a user-friendly name for the driver (e.g. CData JDBC Driver for Impala).
- Set Class Name to the class name for the JDBC driver: cdata.jdbc.apacheimpala.ApacheImpalaDriver.
- Set URL Template to jdbc:apacheimpala:.
- In the Libraries tab, click "Add File," navigate to the "lib" folder in the installation directory (C:\Program Files\CData[product_name] XXXX\) and select the JAR file (cdata.jdbc.ApacheImpala.jar).
Create a Connection to Impala Data
Follow the steps below to add credentials and other required connection properties.
- In the "Database" menu, click "New Database Connection."
- In the "Connect to a database" wizard that results, select the driver you just created (e.g. CData JDBC Driver for Impala) and click "Next >."
- On the Main tab of the configuration wizard, set the JDBC URL, using the required connection properties:
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;
- Click "Test Connection ..." to ensure you have configured the connection properly.
- Click "Finish."
Query Impala Data
You can now query information from the tables exposed by the connection: Right-click a Table and then click View Table. The data is available on the Data tab.
