-----------------------------------------------------------------
What's the expected output? It should be able to hold `2^31 - 1` bytes?
According to my investigation
https://github.com/apache/arrow/blob/f9c070162acd87caf031723fb8d7e9c9a7317c0e/cpp/src/arrow/builder.h#L44
limits to `(2^31) - 1`

> Key: ARROW-2367
> URL: https://issues.apache.org/jira/browse/ARROW-2367
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.9.0
> Reporter: Bryant Menn
> Priority: Major
>
> When creating a Pandas dataframe with lists as elements as a column the
> following error occurs when converting to a {{pyarrow.Table}} object.
> {code}
> Traceback (most recent call last):
> File "arrow-2227.py", line 16, in <module>
> arr = pa.array(df['strings'], from_pandas=True)
> File "array.pxi", line 177, in pyarrow.lib.array
> File "error.pxi", line 77, in pyarrow.lib.check_status
> File "error.pxi", line 77, in pyarrow.lib.check_status
> pyarrow.lib.ArrowInvalid: BinaryArray cannot contain more than 2147483646
> bytes, have 2147483647
> {code}
> The following code was used to generate the error (adapted from ARROW-2227):
> {code}
> import pandas as pd
> import pyarrow as pa
> # Commented lines were used to test non-binary data types, both cause the
> same error
> v1 = b'x' * 100000000
> v2 = b'x' * 147483646
> # v1 = 'x' * 100000000
> # v2 = 'x' * 147483646
> df = pd.DataFrame({
> 'strings': [[v1]] * 20 + [[v2]] + [[b'x']]
> # 'strings': [[v1]] * 20 + [[v2]] + [['x']]
> })
> arr = pa.array(df['strings'], from_pandas=True)
> assert isinstance(arr, pa.ChunkedArray), type(arr)
> {code}
> Code was run using Python 3.6 with PyArrow installed from conda-forge on
> macOS High Sierra.
