Steve Yeom commented on HIVE-18395:
-----------------------------------
Currently aggregate queries like "SELECT MAX.." is using MetaStore stats when
appropriate for non-ACID/non-MM tables.
If used for aggregate queries, then it should be accurate.
If used for an ACID or MM table, then snapshot isolation should be guaranteed
since it is a regular SQL query.
> Using stats for aggregates on Acid/MM is off even with
> "hive.compute.query.using.stats" is true.
