Enhancements
  • The driver has been updated with OpenSSL library version 1.0.2n, which addresses the following security vulnerabilities:*
    • rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
    • Read/write after SSL object in error state (CVE-2017-3737)
    • bn_sqrx8x_internal carry bug on x86_64 (CVE-2017-3736)
    • Malformed X.509 IPAddressFamily could cause OOB read (CVE-2017-3735)

    Version 1.0.2n also addresses the following vulnerabilities resolved by earlier versions of the library.

    For more information on the OpenSSL vulnerabilities resolved by this upgrade, refer to the corresponding OpenSSL announcements at https://www.openssl.org/news/vulnerabilities-1.0.2.html.
  • The Batch Mechanism connection option has been added to the driver. When BatchMechanism is set to 2 (MultiRowInsert), the driver executes a single insert for all the rows contained in a parameter array. MultiRowInsert is the default setting and provides substantial performance gains when performing batch inserts.
  • The driver has been enhanced to support SSL encryption, which can be configured using the following new connection options: Crypto Protocol Version, CrypoLibName, Encryption Method, Host Name in Certificate, Key Password, Key Store, Key Store Password, SSLLibName, Trust Store, Trust Store Password, Validate Server Certificate. SSL support was formally certified against driver version 07.16.0317 (B0386, U0249).
  • Support for Kerberos Authentication.
  • The driver has been enhanced to support the Char, Decimal, and Varchar data
    types when connected to Impala 2.0 and higher.
  • The ArraySize connection option has been refreshed to allow specifying
    the number of cells retrieved instead of rows. By determining the fetch size
    based on the number of cells, the driver can avoid out of memory errors when
    fetching from tables containing a large number of columns.
Changed Behavior
  • The AuthenticationMethod connection option has been refreshed with a new valid value for enabling Kerberos Authentication. To use Kerberos  authentication with the driver, set AuthenticationMethod=4.

Version 7.1.5

Certifications
  • Certified with Red Hat Enterprise 7.0
  • Certified with CentOS Linux 7.0
  • Certified with Oracle Linux 7.0
  • Certified with Cloudera Impala Server 1.1, 1.2, 1.3, 1.4
  • Certified with Cloudera Impala Server 2.0, 2.1

Version 7.1.4

Certifications
  • Certified with Windows 8.1
Enhancements
  • The new KeepAlive connection option allows you to use TCP Keep Alive to maintain idle TCP connections.

Version 7.1.3

Certifications
  • Certified with CentOS Linux 4.x, 5.x, and 6.x
  • Certified with Oracle Linux 4.x, 5.x, and 6.x

Version 7.1.2

Supported with the following Apache Hive versions:
  • Certified with Cloudera Impala 1.0 database server and formally certified with the following File formats and storage handlers:
    • File Formats:Parquet, Text File
    • Storage Handlers:HBase
Features
  • Returns result set metadata for parameterized statements
    that have been prepared but not yet executed.
  • Supports parameter arrays, processing the arrays as a series of
    executions, one execution for each row in the array.
  • Provides a connection option that allows you to configure
    the driver to report that it supports transactions, although
    Hive does not support transactions. This provides a workaround
    for applications that do not operate with a driver that reports
    transactions are not supported.
  • Provides a connection option that allows you to set a default limit for
    the number of rows returned when an ORDER BY clause is submitted. This
    provides a workaround for applications that are not compatible with
    Impala's requirement that ORDER BY clauses limit the number of rows returned.
  •  The driver provides support for the following standard SQL
    functionality:
    • Create Index, Create Table, and Create View
    • Insert, Update, and Delete
    • Drop Index and Drop Table
