[jira] [Created] (HIVE-5866) Hive divide operator generates wrong results in certain cases

Xuefu Zhang created HIVE-5866:
---------------------------------

             Summary: Hive divide operator generates wrong results in certain cases
                 Key: HIVE-5866
                 URL: https://issues.apache.org/jira/browse/HIVE-5866
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.13.0
            Reporter: Xuefu Zhang
            Assignee: Xuefu Zhang


Current GenericUDFOPDivide seems having a bug. The following query generates NULL result.
{code}
hive> select 4BD / 25BD  from test limit 1;        
...
Total MapReduce CPU Time Spent: 890 msec
OK
NULL
Time taken: 7.901 seconds, Fetched: 1 row(s)
{code}

The correct result should be 0.16 in this query.
