----------------------------------------
Summary: SegFault in pyarrow.parquet.write_table with specific
options
Key: ARROW-2082
URL: https://issues.apache.org/jira/browse/ARROW-2082
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.8.0
Environment: tested on MacOS High Sierra with python 3.6 and Ubuntu
Xenial (Python 3.5)
Reporter: Clément Bouscasse
I originally filed an issue in the pandas project but we've tracked it down to
arrow itself, when called via pandas in specific circumstances:
[https://github.com/pandas-dev/pandas/issues/19493]
basically using
{code:java}
df.to_parquet('filename.parquet', flavor='spark'){code}
gives a seg fault if `df` contains a datetime column.
Under the covers, pandas translates this to the following call:
{code:java}
pq.write_table(table, 'output.parquet', flavor='spark', compression='snappy',
coerce_timestamps='ms')
{code}
which gives me an instant crash.
There is a repo on the github ticket.
