The driver has been enhanced to include timestamp in the Spy and JDBC packet logs by default. If required, you can disable the timestamp logging by specifying the following at connection: For Spy logs, set spyAttributes=(log=(file)Spy.log;timestamp=no)
and for JDBC packet logs, set ddtdbg.ProtocolTraceShowTime=false.
Interactive SQL for JDBC (JDBCISQL) is now installed with the product. JDBCISQL is a command-line interface that supports connecting your driver to a data source, executing SQL statements and retrieving results in a terminal. This tool provides a
method to quickly test your drivers in an environment that does not support GUIs.*
The driver has been enhanced to support SSL data encryption. Refer to the readme for more information.*
The driver has been enhanced to support the Char and Vachar data type with Cloudera Impala 2.1 and higher.
Support for result set holdability has been added to the driver.
Java SE 7 has reached the end of its product life cycle and will no longer receive generally available security updates. As a result, the drivers will no longer support JVMs that are version Java SE 7 or earlier. Support for distributed versions of
Java SE 7 and earlier will also end, including IBM SDK (Java Edition).*
The driver no longer registers the Statement Pool Monitor as a JMX MBean by default. To register the Statement Pool Monitor and manage statement pooling with standard JMX API calls, the new RegisterStatementPoolMonitorMBean connection property must be set to true.*
GA Release Features
Supports SQL read-write access to Cloudera Impala 1.3 and higher
Includes the TransactionMode connection property which allows you to configure the driver to report that it supports transactions, even though Hive does not support transactions. This provides a workaround for applications which do not operate with
a driver that reports transactions are not supported.
