The CREATE EXTERNAL TABLE examples given in the document assume a default pxf hadoop server has been configured in /usr/local/pxf-gp6/servers/default. The examples will fail if a default hadoop pxf server has not been configured.
The document should mention (where the examples are given) that "If your PXF server configuration does not include a default server, please use the SERVER= parameter to specify the PXF server configuration to use. For more information about configuring PXF server configuration files see Configuring PXF Servers."
