Furkan Tektas updated ARROW-6520:
---------------------------------
Description:
I'm not sure if this should be reported to Parquet or here.
When I tried to serialize a pyarrow table with a fixed size binary field (holds
16 byte UUID4 information) to a parquet file, segmentation fault occurs.
Here is the minimal example to reproduce:
{{import pyarrow as pa}}
{{ from pyarrow import parquet as pq}}
{{ data = \{"col": pa.array([b"1234" for _ in range(10)])}}}
{{ fields = [("col", pa.binary(4))]}}
{{ schema = pa.schema(fields)}}
{{ table = pa.table(data, schema)}}
{{ pq.write_table(table, "test.parquet")}}
{{ segmentation fault (core dumped) ipython}}
Yet, it works if I don't specify the size of the binary field.
{{import pyarrow as pa}}
{{from pyarrow import parquet as pq}}
{{data = \{"col": pa.array([b"1234" for _ in range(10)])}}}
{{fields = [("col", pa.binary())]}}
{{schema = pa.schema(fields)}}
{{table = pa.table(data, schema)}}
{{pq.write_table(table, "test.parquet")}}
Thanks,
