- Certified with CentOS Linux 7.1
- Certified with Oracle Linux 7.1

cluster by defining user roles and permissions.
- 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.
- 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.

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
- 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
- Create Index, Create Table, and Create View
- Insert, Update, and Delete
- Drop Index and Drop Table
