Keith Curtis created ARROW-1311:
-----------------------------------
Summary: python hangs after write a few parquet tables
Key: ARROW-1311
URL: https://issues.apache.org/jira/browse/ARROW-1311
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.5.0
Environment: Python 3.5.2, pyarrow 0.5.0
Reporter: Keith Curtis
I had a program to read some csv files (a few million rows each, 9 columns),
and converted with:
```python
import os
import pandas as pd
import pyarrow.parquet as pq
import pyarrow
def to_parquet(output_file, csv_file):
df = pd.read_csv(csv_file)
table = pyarrow.Table.from_pandas(df)
pq.write_table(table, output_file)
```
The first csv file would always complete, but python would hang on the second
or third file, and sometimes on a much later file.
