Description

HIVE-7679 is not doing the correct thing. The scale down/up factor updating column stats was wrong as ratio = newRowCount/oldRowCount is always infinite (oldRowCount = 0). The old row count should be retrieved from parent corresponding to the current column whose statistics is being updated.
