> HIVE-2693 introduced support for Decimal datatype in Hive. However, the current implementation
has unlimited precision and provides no way to specify precision and scale when creating the
table.
> For example, MySQL allows users to specify scale and precision of the decimal datatype
when creating the table:
> {code}
> CREATE TABLE numbers (a DECIMAL(20,2));
> {code}
> Hive should support something similar too.
