-----------------------------------
Summary: [Python] from_pandas fails when converting decimals if
contain None
Key: ARROW-2432
URL: https://issues.apache.org/jira/browse/ARROW-2432
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.9.0
Reporter: Bryan Cutler
Using from_pandas to convert decimals fails if encounters a value of {{None}}.
For example:
{code:java}
In [1]: import pyarrow as pa
...: import pandas as pd
...: from decimal import Decimal
...:
In [2]: s_dec = pd.Series([Decimal('3.14'), None])
In [3]: pa.Array.from_pandas(s_dec, type=pa.decimal128(3, 2))
---------------------------------------------------------------------------

ArrowInvalid: Error converting from Python objects to Decimal: Got Python
object of type NoneType but can only handle these types: decimal.Decimal
In [4]: s_dec
Out[4]:
0 3.14
1 None
dtype: object{code}
The above error is raised when specifying decimal type. When no type is
specified, a seg fault happens.
This previously worked in 0.8.0.
