Robert Dailey updated ARROW-1938:
-
Description:
I receive the following error after upgrading to pyarrow 0.8.0 when writing to
a dataset:
* ArrowIOError: Column 3 had 187374 while previous column had 1
The command was:
write_table_values = {'row_group_size': 1}
pq.write_to_dataset(pa.Table.from_pandas(df, preserve_index=True),
'/logs/parsed/test', partition_cols=['Product', 'year', 'month', 'day',
'hour'], **write_table_values)
I've also tried write_table_values = {'chunk_size': 1} and received the
same error.
This same command works in version 0.7.1. I am trying to troubleshoot the
problem but wanted to submit a ticket.
