[ANNOUNCE] New Cloudera ODBC v2.6.4 Driver for Apache Impala Released

[ANNOUNCE] New Cloudera ODBC v2.6.4 Driver for Apache Impala Released

Cloudera Employee

We are pleased to announce the release of Cloudera ODBC v2.6.4 driver for Apache Impala.  The release has the following fixes and enhancements:


Enhancements & New Features

[0013885][IMP-601] The driver now supports the use of SERVER as an alias for the HOST configuration options. The configuration option HOST is still supported.


[IMP-607] The driver has been updated to use version 1.1.0 of the RapdJSOn parser.


Resolved Issues

[00139182][IMP-603] in some queries that include aliases in subqueries, the driver translates the query to a syntax that is not supported by Impala CDH6.


Workflow Changes: The following changes may disrupt workflows from earlier versions.

  • 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.
