> Key: HIVE-8648
> URL: https://issues.apache.org/jira/browse/HIVE-8648
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.0, 0.14.0, 0.13.1
> Reporter: Brock Noland
> Assignee: Brock Noland
> Attachments: HIVE-8648.1.patch

>
> 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.
