> We worked hard towards faster update stats for columns of a partition of a table previously
HIVE-7736
> and HIVE-7876
> Although there is some improvement, it is only correct in the first run. There will be
duplicate column stats later. Thanks to Eugene Koifman 's comments.
> We fixed this in HIVE-7944 by reversing the patch.
> This JIRA ticket is my another try to improve the speed.
