----------------------------------
Summary: pandas ArrowInvalid message should include failing column
name
Key: ARROW-2626
URL: https://issues.apache.org/jira/browse/ARROW-2626
Project: Apache Arrow
Issue Type: Improvement
Reporter: Louis Potok
When writing a pandas dataframe to feather using its to_feather method,
sometimes a single column's conversion fails in pandas_compat.convert_column,
which leads the whole method to fail. The error message should include the name
of the column that failed for easier debugging.
Eg instead of:
{code:java}
ArrowInvalid: Error converting from Python objects to String/UTF8: Got Python
object of type int but can only handle these types: str, bytes.
{code}
Throw:
{code:java}
ArrowInvalid: Error converting from Python objects to String/UTF8: Got Python
object of type int but can only handle these types: str, bytes. (column
"user_id")
{code}
