Steve Yeom commented on HIVE-18395:
-----------------------------------
The preview version "HIVE-18395.01.preview" works for a main success flow for
executing
"select COUNT(*) and COUNT(col-name)" using table and column stats only
with hive.stats.autogether=true and hive.stats.column.autogather=true
for non-partitioned tables. But internally in metastore updating
non-partitioned table stats is
the same as single-partitioned table.
> Using stats for aggregate query on Acid/MM is off even with
> "hive.compute.query.using.stats" is true.
