When I sum() a decimal18, I used to get result with P18, with this build, I 
only get P9. Looks like a regression.

Here is the query through drill:

0: jdbc:drill:schema=dfs> select sum(cast(c_decimal9 as decimal(18,9))) from 
data;
+------------+
|   EXPR$0   |
+------------+
| 1.23582883E8 |
+------------+

And I used to get

1.2358288447063999E8
