Key: FLINK-4795
URL: https://issues.apache.org/jira/browse/FLINK-4795
Project: Flink
Issue Type: Bug
Components: Python API
Reporter: Yakov Goldberg
CsvStringify crashes in case of tuple in tuple, t.e. ("a", True, (1,5))
Looks like, mistyping in CsvStringify._map()
def _map(self, value):
if isinstance(value, (tuple, list)):
return "(" + b", ".join([self.map(x) for x in value]) + ")"
else:
return str(value)
self._map() should be called
But this will affect write_csv() and read_csv().
write_csv() will work automatically
and read_csv() should be implemented to be able to read Tuple type.
