Stefania commented on CASSANDRA-11631:
--------------------------------------

Thanks for the patch, I've backported it and enhanced it to cover composite types and better
error reporting:

Here are the new tests: https://github.com/riptano/cassandra-dtest/pull/949

Inserting {{None}} values in collections, e.g. lists, resulted in server side assertion errors.
[~snazy] could you review the final patch and do you think we should do anything about empty
values in collections (like ignoring them) or is a parse error indicating the problematic
field sufficient?

> cqlsh's {{COPY FROM ... WITH PREPAREDSTATEMENTS = False}} fails if the row contains null
values. Reason is that the {{','.join(r)}} in {{make_non_prepared_batch_statement}} doesn't
seem to handle {{None}}, which results in this error message.
> {code}
> Failed to import 1 rows: TypeError - sequence item 2: expected string, NoneType found,
 given up without retries
> {code}
> Attached patch should fix the problem.
