2.12.1 =======================================================================$$$$$$Released 2026-7-17$$$$$$ * [SPARKO-1847] Updated third-party libraries$$$$$$ The connector now uses the following third-party libraries:$$$ - Expat 2.8.2 (previously 2.8.1)$$$ - libcURL 8.21.0 (previously 8.20.0)$$$$$$$$$Known Issues$$$The following are known issues that you may encounter due to limitations in$$$the data source; the connector; or an application.$$$$$$ * [SPARKO-1404] When querying tables that contain VOID columns; the server$$$ returns an error.$$$$$$ * [SPARKO-1101] When the Auth_AccessToken line length is longer than the$$$ maximum limit of 1000; the connector returns an authentication error. For$$$ more information; see the Installation and Configuration Guide.$$$$$$ * [SPARKO-879] When connecting to a server that supports multiple catalogs;$$$ the connector no longer reports the catalog for schemas and tables as$$$ SPARK.$$$$$$ The Spark server now reports the catalog.$$$$$$ * [SPARKO-670] In some cases; when retrieving timestamp data; the connector$$$ returns an error.$$$$$$ In some cases; when connecting to certain distributions of$$$ Apache Spark; the connector returns the following error: Conversion from$$$ number to string failed due to undersized character buffer. This issue$$$ affects versions 2.6.12 to 2.6.14 of the Spark ODBC connector.$$$$$$ As a workaround; set EnableArrow=0 in the connection string or DSN.$$$$$$ * [SPARKO-620] Issue with date and timestamp before the beginning of the$$$ Gregorian calendar when connecting to Spark 2.4.4 or later; or versions$$$ previous to 3.0; with Arrow result set serialization.$$$$$$ When using Spark 2.4.4 or later; or versions previous to Spark 3.0; DATE$$$ and TIMESTAMP data before October 15; 1582 may be returned incorrectly if$$$ the server supports serializing query results using Apache Arrow. This$$$ issue should not impact most distributions of Apache Spark.$$$$$$ To confirm if your distribution of Spark 2.4.4 or later has been impacted$$$ by this issue; you can execute the following query:$$$$$$ SELECT DATE 1581-10-14$$$$$$ If the result returned by the connector is 1581-10-24; then you are$$$ impacted by the issue. In this case; if your data set contains date and/or$$$ timestamp data earlier than October 15; 1582; you can work around this$$$ issue by adding EnableArrow=0 in your DSN or connection string to disable$$$ the Arrow result set serialization feature.$$$$$$ * When retrieving data from a BINARY column; a ClassCastException error$$$ occurs.$$$$$$ In Spark 1.6.3 or earlier; the server sometimes returns a$$$ ClassCastException error when attempting to retrieve data from a BINARY$$$ column.$$$$$$ This issue is fixed as of Spark 2.0.0.$$$$$$ For more information; see the JIRA issue posted by Apache named When$$$ column type is binary; select occurs ClassCastException in Beeline at$$$ https://issues.apache.org/jira/browse/SPARK-12143.$$$$$$$$$Workflow Changes =============================================================$$$$$$The following changes may disrupt established workflows for the connector.
