Announcing: Impala ODBC v2.5.23 and JDBC v2.5.16 Drivers

Master Collaborator

Hello CDH and Impala Users,


We are pleased to announce the release of the Impala ODBC v2.5.23 and JDBC v2.5.16 drivers.


The Impala ODBC driver now supports authentication using user credentials without SASL implemented and fixes the following issues:

  • SQLDescribeCol returns incorrect column lengths

  • Windows DSN Setup dialog loads and saves the password from/to a DSN

  • The driver may hang when running concurrent operations using the same connection from different threads

The Impala JDBC driver fixes the following issues:

  • Driver misinterprets a newer version of Impala

  • Executing a query after PreparedStatement.setObject(1, null) in Native Query Mode causes a null pointer issue to occur

  • Driver does not return an error when a table or column in a query is not found

These drivers work for previous versions of HiveServer2 in CDH 4.1 or higher and Impala 1.0 or higher.
