Review request for hive.
Summary
-------
If all of the distinct params are in group by keys, union column reserved for
distinct params would not be added, which making problems initializing RS
operator.
This patch is just a simple bypass adding dummy expression for the union
column. Someone would know better way to resolve the problem.
This addresses bug HIVE-2332.
