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`;
+------------+---------------------------+
| Fragment | Number of records written |
+------------+---------------------------+
| 0_0 | 15000 |
+------------+---------------------------+
1 row selected (1.977 seconds)
{code}
However, when I try to read from the new created parquet file, Drill report
IOBE in parquet reader.
{code}
select * from my_dec_table;
Query failed: Query stopped., index: 22531, length: 1 (expected: range(0,
22531)) [ ee35bc67-5c70-4677-bf7f-8db12e4a5491 on 10.250.0.8:31010 ]
{code}
The plan looks fine to me for this query:
{code}
xplain plan for select * from my_dec_table;

columns=[`*`]]])
{code}
Here is part of the stack trace:
