The new AllowedOpenSSLVersions option allows you to determine which version of the OpenSSL library file the driver uses for data encryption. See AllowedOpenSSLVersions or Designating an OpenSSL Library for details.
The driver has been enhanced to support ACID operations for Inserts, Updates, and Deletes on servers that are configured to use them. See Limitations on Apache Hive Functionality for more information on limitations and restrictions.
The driver has been enhanced to support Apache ZooKeeper, which can be configured using the refreshed Host Name connection option and the new ZookeeperDiscovery and ZookeeperNamespace connection options. See Apache ZooKeeper, Host Name, Zookeeper Discovery , and Zookeeper Namespace for details.
The following Windows platforms have reached the end of their product lifecycle and are no longer supported by the driver:
Windows 8.0 (versions 8.1 and higher are still supported)
Windows Vista (all versions)
Windows XP (all versions)
Windows Server 2003 (all versions)
Changes for 8.0.1 GA
Driver Enhancements
The driver has been enhanced to support HTTP mode, which allows you to access Apache Hive data stores using HTTP/HTTPS requests. HTTP mode can be configured using the new Transport Mode and HTTP Path connection options. See HTTP Mode, Transport Mode, and HTTP Path for details.
The driver has been enhanced to support session cookie based authentication for HTTP connections. Cookie based authentication can be configured using the new Enable Cookie Authentication and Cookie Name connection options. See Enable Cookie Authentication, and Cookie Name.
The driver has been enhanced to support HTTP connections to Apache Knox gateways. See Apache Knox for details.
The new Array Insert Size connection option provides a workaround for memory and server issues that can sometimes occur when inserting a large number of rows that contain large values. See Array Insert Size for details.
Changed Behavior
The Array Size (ArraySize) connection option has been renamed Array Fetch Size (ArrayFetchSize). The ArraySize attribute will continue to be supported for this release, but will be deprecated in subsequent versions of the product. See Array Fetch Size for details.
Changes for 8.0.0 GA
Driver Enhancements
The driver has been enhanced to optimize the performance of fetches.
The new Min Long Varchar Size connection option allows you to fetch SQL_LONGVARCHAR columns whose size is smaller than the minimum imposed by some third-party applications, such as SQL Server Linked Server. See Min Long Varchar Size for details.
The new Varchar Threshold connection option allows you to fetch columns that would otherwise exceed the upper limit of the SQL_VARCHAR type for some third-party applications, such as SQL Server Linked Server. See Varchar Threshold for details.
The new Max String Size connection option allows you to determine the maximum size of columns of the String data type that the driver describes through result set descriptions and catalog functions. This option replaces the Max Varchar Size connection option. See Max String Size for details.
The new Catalog Mode connection option allows you to determine whether the driver uses native catalog functions to retrieve information returned by the SQLTables, SQLColumns, and SQLStatistics catalog functions. In the default setting, the driver employs a balance of native functions and driver-discovered information for the optimal balance of performance and accuracy when retrieving catalog information. This option replaces the Use Native Catalog Functions option. See Catalog Mode for details.
The driver includes a new Tableau data source file (Windows only) that provides improved functionality when accessing your data with Tableau. Refer to the Windows Quick Start for details.
The driver supports Hive versions 1.0 and higher. Support has been deprecated for earlier versions of Hive. See About the Apache Hive Driver for details.
Support has been deprecated for the following distributions:
The Use Native Catalog Functions connection option has been replaced by the new Catalog Mode connection option. The UseNativeCatalogFunctions attribute will continue to be supported for this release, but will be deprecated in subsequent versions of the product. See Catalog Mode for details.
The Max Varchar Size connection option has been replaced by the new Max String Size connection option. The MaxVarcharSize attribute will continue to be supported for this release, but will be deprecated in subsequent versions of the product. See Max String Size for details.
The Authentication Method connection option has been refreshed with a new valid value for enabling Kerberos Authentication. To use Kerberos authentication with the driver, set AuthenticationMethod=4. See Authentication Method for details.
Specifying the legacy setting for enabling Kerberos (AuthenticationMethod=1) will return an error message at connection.
The default value for Crypto Protocol Version has been updated to TLSv1.2,TLSv1.1,TLSv1. This change improves the security of the driver by employing only the most secure cryptographic protocols as the default behavior. See Crypto Protocol Version for details.
The valid and default values for the String Describe Type connection have been updated:
