>    Affects Versions: 0.13.0, 0.14.0, 0.13.1

> Since HIVE-3777 users who want to set the number of rows for a table, must do as follows:
> {noformat}
> alter table ... set tblproperties ('numRows' = '12345', 'STATS_GENERATED_VIA_STATS_TASK' = 'true');
> {noformat}
> Which is strange because (1) users can know the numbers of rows and (2) the stat is not generated by a stats task.
