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 10000 The command was: write_table_values = {'row_group_size': 10000} 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) This same command works in version 0.7.1. I am trying to troubleshoot the problem but wanted to submit a ticket. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
