            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.

Versions 2.5 and 2.0 of the Cloudera ODBC Connector
                    use the HiveServer2 protocol, corresponding to Impala port 21050.

                    original HiveServer1 protocol, corresponding to Impala port 21000.
