Configuring ODBC for Impala

Download and configure the ODBC driver to integrate your applications with Impala.

Impala has been tested with the Impala ODBC driver version 2.5.42, and Cloudera recommends that you use this version with the current version of Impala.

  1. Download and install an ODBC driver.
  2. Configure the ODBC port.
    Versions 2.5 and 2.0 of the Cloudera ODBC Connector use the HiveServer2 protocol, corresponding to Impala port 21050.
    Version 1.x of the Cloudera ODBC Connector uses the original HiveServer1 protocol, corresponding to Impala port 21000.
