Connecting to Impala from Connect for Big Data requires the following configuration components:
- Impala JDBC connection
- Impala table staging
- Apache Sentry authorization when applicable
Impala JDBC connection
To connect to Impala via JDBC on Windows at design time, download the JDBC driver and specify the mandatory driver name and driver class path parameters in the JDBC configuration file:
See Configuring Impala to Work with JDBC.
- Set the driver name and driver class path in the JDBC configuration file.
Impala table staging
When reading Impala sources and writing Impala targets, Connect for Big Data stages the data as a text-backed Impala table.
To stage the tables, sufficient space and CREATE TABLE privileges are required.
