Bryan Cutler created ARROW-2101:
-----------------------------------
Summary: [Python] from_pandas reads 'str' types as binary Arrow
data with Python 2
Key: ARROW-2101
URL: https://issues.apache.org/jira/browse/ARROW-2101
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.8.0
Reporter: Bryan Cutler
Using Python 2, converting Pandas with 'str' data to Arrow results in Arrow
data of binary type, even if the user supplies type information. conversion of
'unicode' type works to create Arrow data of string types. For example
{code}
In [25]: pa.Array.from_pandas(pd.Series(['a'])).type
Out[25]: DataType(binary)
In [26]: pa.Array.from_pandas(pd.Series(['a']), type=pa.string()).type
Out[26]: DataType(binary)
In [27]: pa.Array.from_pandas(pd.Series([u'a'])).type
Out[27]: DataType(string)
{code}
