Namit Jain commented on HIVE-1752:
----------------------------------
Copying from HIVE-1750,
For eg, if T is partitioned on ds,
and the query is:
select c1 from T where ds = '1' and c2 > 10;
there is no reason to add 'ds' to each row
> Avoid UnionStructObjectInspector for partition columns when necessary

> Once HIVE-1750 is finished, union struct for partition columns and normal
> columns is not needed anymore. We can save some costs by not having the
> struct.
