You can use a JDBC or ODBC client to connect to Impala and run queries against data stored in MapR-FS, MapR-DB, and HBase. Before you connect to Impala from a JDBC or ODBC application, configure the client machine that you want to connect from. How you configure the machine depends on the type of application you use.

JDBC

The MapR Impala JDBC Driver is available in a JAR file. You can download the driver to access Impala from a Java application or any tool that uses a JDBC connection.

ODBC

The MapR Impala ODBC Driver is available for Microsoft Windows, Linux, and Mac OS X. The driver complies with the ODBC 3.52 data standard and adds Unicode and 32- and 64-bit support on all platforms. The ODBC driver connects to an Impala server regardless of the server’s host operating system.
