> cqlsh: COPY FROM ignores NULL values in conversion

> Key: CASSANDRA-11549
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11549
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Reporter: Stefania
> Assignee: Stefania
> Fix For: 2.1.x, 2.2.x, 3.0.x, 3.x
>
>
> 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}
