Damien Carol updated HIVE-8061:
-------------------------------
Description:
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.
