>             Project: Apache HAWQ
>          Issue Type: Improvement
>          Components: PXF

> In HAWQ-45, we've updated pxf name space to org.apache.hawq.
> Given the legacy version of PXF might have existed with the old namespace table definition, it'd be good to have error messages like "com.pivotal.pxf was an old namespace used in the previous versions, please switch to org.apache.pxf as the new namespace and update your table definitions." during *SELECT..." or "UPDATE..." table queries.
> This is an addition to current error detection logic only when we figured users were using the old namespace.
> The error message should apply to both READ and WRITE pxf tables.
