[HIVE-8648] numRows cannot be set by user

• Type: Bug
• Status: Open

Description

Since HIVE-3777 users who want to set the number of rows for a table, must do as follows:

alter table ... set tblproperties ('numRows' = '12345', 'STATS_GENERATED_VIA_STATS_TASK' = 'true');

Which is strange because (1) users can know the numbers of rows and (2) the stat is not generated by a stats task.
