    Version 5.1.4

    ENHANCEMENTS
    • 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. For details, refer to Data Types.
    • Support for result set holdability has been added to the driver.
    CHANGED BEHAVIOR
    • 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. For details, refer to RegisterStatementPoolMonitorMBean.*

    Version 5.1.3

    GA Release Features
    • Supports SQL read-write access to Cloudera Impala
    • 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.
    • Support for connection pooling
