About the Impala JDBC driver

A JDBC driver is a Java .jar library that lets applications connect to Impala. DbSchema uses JDBC to reverse engineer schemas, run SQL, and generate documentation. Driver files are usually published by the database vendor or an open-source project.

JDBC URL format

Host, port, database name, and SSL options are passed in a URL starting with jdbc:. Each Impala driver uses its own syntax — see the connection details below.

The Impala JDBC driver

Apache Impala is Cloudera's massively parallel processing (MPP) SQL engine for Hadoop, enabling interactive SQL queries over HDFS and HBase without moving data. It is optimized for low-latency BI queries against Parquet and ORC files in the Cloudera Data Platform.

The Apache Impala JDBC URL

  • Required File(s): ImpalaJDBC42.jar
  • Java Driver Class: com.cloudera.impala.jdbc.Driver
  • JDBC URL: jdbc:impala://HOST:PORT/DB
  • Website: Cloudera Impala

Download Impala JDBC Driver

The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.

DbSchema and Apache Impala

DbSchema connects to Impala using the Cloudera JDBC driver and renders Impala tables with partition definitions and storage format information. Use the SQL Editor to write Impala SQL with partition pruning and query hints for columnar format queries.

Test the driver with DbSchema

Use Impala visually in DbSchema

After the JDBC driver connects, you get ER diagrams, SQL editor, schema sync, and HTML documentation in one desktop app. Compare DbSchema editions.

ER diagrams

Reverse engineer Impala into an interactive diagram and edit structures visually.

SQL & query builder

Run SQL with autocomplete or compose queries without writing every join by hand.

Schema documentation

Export HTML docs your team can browse without installing DbSchema.
