Ted-Jiang opened a new issue, #3140:
URL: https://github.com/apache/arrow-datafusion/issues/3140
**Describe the bug**
I found in our env `approx_percentile_cont` return different result when
running the same query.
```DataFusion CLI v10.0.0
❯ create external table line STORED AS PARQUET LOCATION
'/Users/yangjiang/test-data/tpch-1g-oneFile' ;
❯ select o_orderstatus, approx_percentile_cont(o_totalprice, 0.5) from
order group by o_orderstatus order by 1 limit 5 ;
❯ create external table order stored as parquet location
'/Users/yangjiang/test-data/tpch-1g/orders';
0 rows in set. Query took 0.043 seconds.
❯ select o_orderstatus, approx_percentile_cont(o_totalprice, 0.5) from
order group by o_orderstatus order by 1 limit 5 ;
