[ANNOUNCE] New Hive ODBC, Impala ODBC and JDBC drivers released

We are pleased to announce the release of Hive ODBC v2.5.21, Impala ODBC v2.5.36, and Impala JDBC v2.5.35.

Resolved issues in Impala JDBC 2.5.35

  • The driver does not properly detect a TOP statement and inserts a TOP 0 before it to generates the limit 0 query. This happens if there is an additional space in the query before the original TOP. This issue has been resolved.

  • Queries with YEAR and ISO_WEEK functions failing due to a data type mismatch. This issue has been resolved.

Please see below links for details on all of the fixes and enhancements

Enhancements and new features in Impala ODBC 2.5.36

  • Support added for Kerberos delegation You now have the option for the driver to forward the user credentials to the server when using Kerberos authentication.

  • Support for Windows Trust Store You now have the option to use the CA certificates in the Windows Trust Store for server verification when using SSL.

  • Auto Reconnect You can configure the driver to automatically attempt reconnection to the Impala server if communications are lost.

  • Support for query, login, and connection timeout The driver now supports the following ODBC API calls: • SQL_ATTR_CONNECTION_TIMEOUT • SQL_ATTR_LOGIN_TIMEOUT • SQL_ATTR_QUERY_TIMEOUT [14244] Optimization of metadata retrieval

Resolved issues in Impala ODBC v2.5.36

  • If a user attempted to connect without proper permissions to access the schema set in the connection string, the driver would fail to connect.   The driver will now display a warning under these circumstances, and use the default schema.

  • Specifying an alias for a column name in the SELECT list when SELECT DISTINCT is present and using that column name in the ORDER BY clause causes a system message to be displayed.

  • Driver returning incorrect order for character data types in the SQLGetTypeInfo result set under some circumstances.
