Known Issues and Workarounds

The following section describes the current known issue for Cloudera Connector for Netezza.

The Boolean data type 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'.

Workaround: 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.
