Known Issues and Work Arounds
— The Boolean datatype format is incompatible between import and export when using direct mode.
When using the Netezza connector in direct mode to import data of type boolean, the format used by the connector is 'T' or 'F' to represent True or False values. However, when doing an export of data from HDFS to Netezza using the connector in direct mode, the expected boolean format is 'TRUE' or 'FALSE'. Work around: Either convert the data to use 'TRUE'/'FALSE' style representation of boolean data values prior to doing a direct mode export, or use the regular mode of export instead of direct mode for this type of data. Expected Resolution: Planned to be fixed in a future release of the connector.
