Description

With HIVE-3976, decimal columns are stored with precision/scale, such as decimal(17,5), as the type name. However, such columns defined in hive prior to HIVE-3976 have a name as "decimal". Those columns need to continue to work with a precision/scale as (10,0), per the functional doc. With patch in HIVE-3976, we may get the following error message in such case:

0: jdbc:hive2://localhost:10000> desc dec;
Error: Error while processing statement: FAILED: RuntimeException Decimal type is specified without length: decimal:int (state=42000,code=40000)

This issue will be addressed in this JIRA as a follow-up task.
