create a test to verify that partition pruning works for partitioned views with a union
---------------------------------------------------------------------------------------

                 Key: HIVE-2513
                 URL: https://issues.apache.org/jira/browse/HIVE-2513
             Project: Hive
          Issue Type: Test
            Reporter: Namit Jain
            Assignee: Namit Jain


It would be good to have a test to check partition pruning on a view like:


create view t1 partitioned on (ds) as
select * from
(
select key, value, ds from t1_new
union all
select key, value, t1_old.ds from t1_old join t1_mapping
on t1_old.keymap = t1_mapping.keymap and
   t1_old.ds = t1_mapping.ds
) subq;


While adding the test, I found that the lineage is broken for this.
Will file a separate issue for that.
