> While running query below against voter_hive (drill table), where contributions field is defined as "float" (4 byte floating point number in drill) I get a value of SUM that is different from result generated by postgres.
> {code}
> select 
>           registration, 
>           age, 
>           name, 
>           sum(contributions) over w  
> from   voter_hive 
> window w AS (partition by registration order by age rows unbounded preceding) 
> order by 
>           registration, 
>           age, 
>           name;
> {code}
> Find attached:
> 1. Query + result generated by Postgres (queries.tar)
> 2. voter_hive parquet file
> 3. create_table.tar - contains CTAS statement + csv file (if you want to create table yourself)
