Subject [jira] [Updated] (CASSANDRA-13364) Cqlsh COPY fails importing Map<String,List<String>>, ParseError unhashable type list
Date Wed, 22 Mar 2017 11:24:41 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-13364?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nicolae N updated CASSANDRA-13364:
----------------------------------
    Description: 
{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_.

_copyutil.py_.
