Subject [jira] [Created] (HIVE-5564) Need to accomodate table decimal columns that were defined prior to HIVE-3976

Xuefu Zhang created HIVE-5564:
---------------------------------

             Summary: Need to accomodate table decimal columns that were defined prior to
HIVE-3976
                 Key: HIVE-5564
                 URL: https://issues.apache.org/jira/browse/HIVE-5564
             Project: Hive
          Issue Type: Task
          Components: Types
    Affects Versions: 0.13.0
            Reporter: Xuefu Zhang
            Assignee: Xuefu Zhang
             Fix For: 0.13.0


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:

{code}
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)
{code}

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