Following queries fail:
```sql
insert overwrite table decimal_1
select cast('17.29' as decimal(4,2)), 3.1415926BD, 3115926.54321BD from src
tablesample (1 rows)
```
`BD` is the suffix for a Hive Big Decimal literal.
```sql
select p_mfgr, p_name, p_size,
min(p_retailprice),
rank() over(distribute by p_mfgr sort by p_name)as r,
dense_rank() over(distribute by p_mfgr sort by p_name) as dr,
p_size, p_size - lag(p_size,1,p_size) over(distribute by p_mfgr sort by
p_name) as deltaSz
from part
group by p_mfgr, p_name, p_size
```
`rank() over(distribute by p_mfgr sort by p_name)as r` now causes a problem.
