> When {{hive.optimize.ppd}} and {{hive.optimize.index.filter}} are turned, and a select
query has a condition on a column that doesn't exist in Parquet file (such as a partition
column), Hive often returns wrong result.
> Please see below example for details:
> {noformat}
> hive> create table test_parq (a int, b int) partitioned by (p int) stored as parquet;
> OK
> Time taken: 0.292 seconds
> hive> insert overwrite table test_parq partition (p=1) values (1, 2);
> OK
> Time taken: 5.08 seconds
> hive> select * from test_parq where a=1 and p=1;
> OK
> 1	2	1
> Time taken: 0.441 seconds, Fetched: 1 row(s)
> hive> select * from test_parq where (a=1 and p=1) or (a=999 and p=999);
> OK
> 1	2	1
> Time taken: 0.197 seconds, Fetched: 1 row(s)
> hive> set hive.optimize.index.filter=true;
> hive> select * from test_parq where (a=1 and p=1) or (a=999 and p=999);
> OK
> Time taken: 0.167 seconds
> hive> select * from test_parq where (a=1 or a=999) and (a=999 or p=1);
> OK
> Time taken: 0.563 seconds
