> If the csv file contains invalid data for collection types, at the moment the data is
imported incorrectly, an error would be a better behavior.
> For example this table:
> {code}
> CREATE TABLE test.test (key text, value frozen<set<text>>, PRIMARY KEY (key));

> {code}
> with this data:
> {code}
> "key1","{'test1', 'test2'}"
> "Key2","not_a_set"
> {code}
> will be imported by {{COPY test.test FROM 'test.csv';}} without errors but will result
in the following data:
> {code}
> cqlsh> select * from test.test;
>  key  | value
> ------+--------------------
>  key1 | {'test1', 'test2'}
>  Key2 |        {'ot_a_se'}
> (2 rows)
> {code}
> The second row should have been rejected. The reason is that the [{{split}} function|https://github.com/stef1927/cassandra/blob/trunk/pylib/cqlshlib/copyutil.py#L1898]
assumes that the first and last characters of the string passed in are parentheses, without
actually checking it.
