> create table t (c decimal(0, 0)) using parquet;
> -- fail with parquet
> -- java.lang.IllegalArgumentException: Invalid DECIMAL precision: 0

> insert into table t values(0);
> -- fail with hive catalog
> -- Caused by: java.lang.IllegalArgumentException: Decimal precision out of
> allowed range [1,38]
> -- at
