> Below are the steps I followed to generate the data :
> {code}
> 1. Generate a parquet file with date column using hive1.2
> 2. Use drill 1.6 to create auto-partitioned parquet files partitioned on the date column
> {code}
> Now the below query returns wrong results :
> {code}
> select i_rec_start_date, i_size from dfs.`/drill/testdata/parquet_date/auto_partition/item_multipart_autorefresh` group by i_rec_start_date, i_size;
> +-------------------+--------------+
> | i_rec_start_date | i_size |
> +-------------------+--------------+
> | null | large |
> | 366-11-08 | extra large |
> | 366-11-08 | medium |
> | null | medium |
> | 366-11-08 | petite |
