Aman Sinha commented on DRILL-1742:
-----------------------------------
+1. Committed fix in master branch: 02d23cb8dc21dfb151aa3d2fc64404c81d0b23cc
Note that the Hive table's row count will be used during planning process but
Drill would still do the aggregation for queries such as 'select count(*) from
table' because the statistics cannot be fully accurate (this is unlike Parquet
where the row count is leveraged to optimize the above query).
> Use Hive stats when planning queries on Hive data sources
