             Summary: sum two or more clumns by sum function
                 Key: HIVE-13154
                 URL: https://issues.apache.org/jira/browse/HIVE-13154
             Project: Hive
          Issue Type: Improvement
    Affects Versions: 1.2.1
            Reporter: lu ping


 I use sum function to get the sum of two  or more columns, but i found the res us wrong. And then i found out that sum function could only get one column sum. I think that if sum function could not compute sum of multiple columns, should give some warning or error? Or else, make sum could summing the values from two or more  columns into one number
