> If I create a parquet file containing two decimal(10,2) columns as:
> {code}
> create table my_dec_table as select *, cast(o_totalprice as decimal(10,2)) dec1, cast(o_totalprice as decimal(10,2)) dec2 from cp.`tpch/orders.parquet`;

> 1 row selected (1.977 seconds)

> However, when I try to read from the new created parquet file, Drill report IOBE in parquet reader.
