> When importing data with the _COPY_ command into a column family that has a
> _map<text, frozen<list<text>>>_ field, I get a _unhashable type: 'list'_
> error. Here is how to reproduce:
> {code}
> CREATE TABLE table1 (
> col1 int PRIMARY KEY,
> col2map map<text, frozen<list<text>>>
> );
> insert into table1 (col1, col2map) values (1, {'key': ['value1']});
> cqlsh:ks> copy table1 to 'table1.csv';
> table1.csv file content:
> 1,{'key': ['value1']}
> cqlsh:ks> copy table1 from 'table1.csv';
> ...
> Failed to import 1 rows: ParseError - Failed to parse {'key': ['value1']} :
> unhashable type: 'list', given up without retries
> Failed to process 1 rows; failed rows written to kv_table1.err
> Processed: 1 rows; Rate: 2 rows/s; Avg. rate: 2 rows/s
> 1 rows imported from 1 files in 0.420 seconds (0 skipped).
> {code}
> But it works fine for Map<String, Set<String>>.
> {code}
> CREATE TABLE table2 (
> col1 int PRIMARY KEY,
> col2map map<text, frozen<set<text>>>
> );
> insert into table2 (col1, col2map) values (1, {'key': {'value1'}});
> cqlsh:ks> copy table2 to 'table2.csv';
> table2.csv file content:
> 1,{'key': {'value1'}}
> cqlsh:ks> copy table2 from 'table2.csv';
> Processed: 1 rows; Rate: 2 rows/s; Avg. rate: 2 rows/s
> 1 rows imported from 1 files in 0.417 seconds (0 skipped).
> {code}
> The exception seems to arrive in _convert_map_ function in _ImportConversion_
> class inside _copyutil.py_.
