[ANNOUNCE] New Hive JDBC Driver Released

We are pleased to announce the release of Hive JDBC v2.6.1  The release has the following enhancements and fixes:

 

Enhancements and New Features in Hive JDBC 2.6.1

  • Improved installation process: Third-party libraries are now bundled with the driver as a shaded jar file.

  • Updated hive-services: The driver has been upgraded to use hive-service-2.0.1 with JDBC 4.1 and hive-service-1.1.1 for JDBC 4.

  • Updated third-party libraries: The driver has been upgraded to use http-client 4.5.3, http-core 4.4.6, commons-codec 1.9, commons-logging 1.2, and Zookeeper 3.4.11.

 

Resolved Issues

  • [00115543] A string literal after a back-tick ( ` ) is treated as a comment.

  • [00115424] When the driver attempts to connect to the server using Beeline, an error occurs on the server and an exception is logged by the driver. This issue has been resolved. Now, when connecting to the server using Beeline, connection properties such as "driver" and "url" are no longer treated as configuration properties for the server, and the driver does not send SET queries to the server with these properties.

  • [00114906] The driver removes query comments and hints when the UseNativeQuery property is set to 1.

 

Breaking Changes

The following are breaking changes to driver functionality. These changes may cause some workflows from earlier versions of the driver to fail.

 

2.6.1 - Removed support for JDBC 3 (Java 5).  

  • Beginning with this release, the driver no longer supports JDBC 3 (Java 5). Only JDBC 4 (Java 6) and JDBC 4.1 (Java 7) are supported.
