Zoltan Haindrich updated HIVE-16495:
------------------------------------
Attachment: HIVE-16495.03.patch
#3) minor changes:
* removed setting stats to 0 - sometimes misinterpreted as good data
* removed resetting partition props to empty...seemed out of place
* more restrictive columnstats task lookup
Note: After alter table there are no statistics for the new columns - I think
this is ok; since if the user have used {{load data}} to add the data; there
might be existing values in these "new" columns.

> ColumnStats merge should consider the accuracy of the current stats
