> COPY FROM fails to import empty values. 
> For example:
> {code}
> $ cat test.csv
> a,10,20
> b,30,
> c,50,60
> $ cqlsh
> cqlsh> create keyspace if not exists test with replication = {'class': 'SimpleStrategy', 'replication_factor':1};
> cqlsh> create table if not exists test.test (t text primary key, i1 int, i2 int);
> cqlsh> copy test.test (t,i1,i2) from 'test.csv';
> {code}
> Imports:
> {code}
> select * from test.test";
>  t | i1 | i2
> ---+----+----
>  a | 10 | 20
>  c | 50 | 60
> (2 rows)
> {code}
> and generates a {{ParseError - invalid literal for int() with base 10: '',  given up without retries}} for the row with an empty value.
> It should import the empty value as a {{null}} and there should be no error:
> {code}
> cqlsh> select * from test.test";
>  t | i1 | i2
> ---+----+------
>  a | 10 |   20
>  c | 50 |   60
>  b | 30 | null
> (3 rows)
> {code}
