> When creating MapR-DB tables with different privileges Drill will return no results for tables with insufficient privileges. Propose an error is returned so the user is aware of the issue, instead of simply no data being returned. 
> This can be a serious issue with complex queries when joining data across multiple data sources.
> Creating 2 tables - one with mapr user and the other as root.
