Apache Impala is a native analytic database for Apache Hadoop. Through JDBC connectivity, Connect for Big Data supports Impala databases as sources and targets when running on the ETL server/edge node, in the cluster, and on a framework-determined node in the cluster.
Connecting to Impala requires configuration steps before the connections can be defined. Connection requirements and behavior differ between Impala sources and targets.
