             Summary: Support specifying scale and precision with Hive decimal type
                 Key: HIVE-3976
                 URL: https://issues.apache.org/jira/browse/HIVE-3976
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor, Types
            Reporter: Mark Grover


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.
