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.
