Query Impala Data in MySQL Workbench

Execute MySQL queries against live Impala data from MySQL Workbench.

You can use the SQL Gateway from the ODBC Driver for Impala to query Impala data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and work with live Impala data in MySQL Workbench.

Connect to Impala Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Impala data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.
