> 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)
> I've also tried write_table_values = {'chunk_size': 10000} 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.
