> virtual column was introduced for supporting bitmap indexing (HIVE-1803) but
> indexing support has been removed by HIVE-18448. At the moment there are no
> real-use cases exercising this virtual column and there are no test cases
> either.
> Moreover, the presence of the column is controlled by hive.exec.rowoffset
> configuration property that has been by default set to false since it's
> introduction to the project.
