We are pleased to announce the release of Cloudera JDBC 2.6.9 driver for Apache Hive The release has the following fixes and enhancements:

Enhancements and New Features

  • [IMP-636] [00144651] [HIVEJ-561] [00146044] [HIVEJ-563] [HIVEJ-554] [HIVEJ-539] Updated third-party libraries. The driver now uses the following third-party libraries:

    • jackson 2.9.9
    • Jackson-datadbind 2.9.9.3
    • Thrift 0.12.0
    • ZooKeeper 3.4.14

  • [HIVEJ-549] Support for JDBC 4.2. The driver now supports JDBC 4.2. For more details see the Installation and Configuration Guide.

  • [HIVEJ-551] New JDBC class names. The driver now supports the following class names for Driver and DataSource that are independent of the JDBC version used:

    • com.cloudera.hive.jdbc.HS1Driver
    • com.cloudera.hive.jdbc.HS2Driver
    • com.cloudera.hive.jdbc.HS1DataSource
    • com.cloudera.hive.jdbc.HS2DataSource

The previous JDBC-version-specific class names for 4.0 and 4.1 are still supported.

  • [00141040] [HIVEJ-545] Renaming join columns. By default, the driver does not allow join columns to be renamed. To enable the renaming of join columns, set the RenameJoinColumn property to “true”.

Resolved Issues

  • [00146521] [HIVEJ-569] The driver resolves the host name to an IP address for SSL verification, causing the host name verification step to fail.
  • [HIVEJ-542] The driver incorrectly treats SSLTrustStore and SSLTrustStorePWD as server-side properties.

Workflow Changes

The following changes may disrupt established workflow for the drivers.

In addition to changes that are already implemented in the current version of the driver, this section describes potentially disruptive changes that will be implemented in a future version of the driver, so that you can plan accordingly.

Upcoming Changes

  • Removing support for JDBC 4 (Java 6). Beginning in the fourth quarter of 2019, the driver will no longer support JDBC 4 (Java 6). For a list of supported JDBC versions, see the Installation and Configuration Guide.

Version 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.
