Connecting to Apache Impala

Establishing a Connection shows how to authenticate to Apache Impala and configure any necessary connection properties in a JDBC URL. You can also configure driver capabilities through the available Connection properties, from data modeling to firewall traversal. The Advanced Settings section shows how to set up more advanced configurations and troubleshoot connection errors.

Connecting to JDBC Data Sources

The CData JDBC Driver for Apache Impala provides full support for integration into Java applications, including Eclipse, NetBeans, IntelliJ IDEA, and many other Integrated Development Environments, as well as J2EE applications running on a Java server such as Tomcat. You can find JSP, console, and swing demos in the installation folder.

Java Version Support

To deploy the driver JAR file, you must have Java Development Kit (JDK) 1.8 or higher installed on your system.

Apache Impala Version Support

The driver models Apache Impala instances as relational databases. The driver leverages the Impala Server Thrift API, to enable bidirectional access to Apache Impala data through SQL. Impala Server 2.2.0 and above are supported.
