Review request for hive, Gunther Hagleitner and Harish Butani.
Bugs: HIVE-7734
https://issues.apache.org/jira/browse/HIVE-7734
Repository: hive-git
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.
