We are pleased to announce the release of Cloudera ODBC v2.6.5 driver for Apache Impala. The release has the following fixes and enhancements:
Enhancements & New Features
[IMP-573] On macOS, you can now use the driver with version 2.3.1 of unixODBC driver manager.
[IMP-628] The driver now uses OpenSSL 1.1.0j.
[IMP-609] The driver now supports Impala versions 1.0.1 through 3.1, and CDH versions 5.0 through 5.16 and 6.0 through 6.1.
[IMP-623] In some cases, queries with a parameterized insert fail.
[IMP-629] The driver does not handle scale and precision of decimal type correctly.
[IMP-612] Driver does not pass a UID into the session when connected using No Authentication.
[IMP-631] The driver incorrectly translates CHAR and VARCHAR types of INSERT values to CAST(CAST(...)). This issue is resolved. The driver now translates these values to a single CAST.
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.
