Review request for hive and Ashutosh Chauhan.


Bugs: HIVE-17934
    https://issues.apache.org/jira/browse/HIVE-17934


Repository: hive-git


Description
-------

* remove the reactive stat state guessing method
* make the guessing only work when a new object is created
* change the way stat objects are merged

this patch will most probably break almost all qtest outputs....
