We are pleased to announce the release of Cloudera ODBC 2.6.8 driver for Apache Impala. The release has the following fixes and enhancements:

Enhancements and New Features

  • [IMP-636] Updated Impala and CDH support. The driver now supports Impala versions 2.7 through 3.3, and CDH version 5.9 through 5.16 and 6.0 through 6.2

  • [IMP-666] Support for DATE data type. The driver now supports the DATE data type for Impala version 3.3 and later. For more information, see “Data Types” in the Installation and Configuration Guide.

Resolved Issues

  • [IMP-686] When an AnalysisException error occurs, the driver incorrectly classifies it as a syntax error and returns SQLState 42000.
  • [IMP-687] After SQLFetech returns and error, if you attempt to call SQLFetch again. The driver terminates unexpectedly.

Known Issues

The following are known issues that you may encounter due to limitations in the data source, the driver, or an application.

Limited Support for BINARY, DATE, and TIME data types.

  • BINARY is not a supported data type in Impala.
  • DATE is supported only when you connect to Impala version 3.3 or later.
  • As a result of the limitations above, some values of TIME data types are also not supported.

Workflow Changes

The following changes may disrupt workflows from earlier versions

Version 2.6.8

[IMP-680] Removed support for earlier versions of Impala and CDH

Beginning with this release, the driver no longer supports Impala 1.0.1 to 2.6 and CDH 5.0 to 5.8. For a list of support versions, see the Installation and Configuration Guide.

Version 2.6.0

Minimum TLS Version

Beginning with this release, the driver requires a minimum version of TLS for encrypting the data store connection. By default, the driver requires TLS version 1.2. This requirement may cause existing DSNs and connection strings to stop working, if they are used to connect to data stores that use a TLS version earlier than 1.2.

To resolve this, in your DSN or connection string, set the Minimum TLS option (the Min_TLS property) to the appropriate version of TLS for your server. For more information, see the Installation and Configuration Guide.
