Sergey Shelukhin commented on HIVE-19820:
-----------------------------------------
Another edge case: some sub-paths of analyze on a non-partitioned table doesn't
include txn data.
After finally adding the check on all the paths making sure that txn stats are
never updated without txn data, I see them failing now... I will update the
patch when I fix all the calls.
> add ACID stats support to background stats updater and fix bunch of edge
> cases found in SU tests

> Follow-up from HIVE-19418.
> Right now it checks whether stats are valid in an old-fashioned way... and
> also gets ACID state, and discards it without using.
> When ACID stats are implemented, ACID state needs to be used to do
> version-aware valid stats checks.
