TODD commented on HIVE-17516:
-----------------------------
Hive version:hive-1.1.0+cdh5.8.3+680
The table agg_unique_visit is rcfile and the data size is 254582438. Create new
table agg_unique_visit_ceshi is orc and the data size is 247463894. I don't
know Why is this so .
> There is something wrong that table data size don't obviously decrease when
> change rcfile to orc .
