-----------------------------------

             Summary: Function concat_ws get a wrong value  
                 Key: HIVE-14918
                 URL: https://issues.apache.org/jira/browse/HIVE-14918
             Project: Hive
          Issue Type: Bug
          Components: UDF
    Affects Versions: 2.0.1, 2.1.0, 2.0.0, 1.1.1
            Reporter: Xiaowei Wang
            Assignee: Xiaowei Wang
            Priority: Critical
             Fix For: 2.1.0


FROM src INSERT OVERWRITE TABLE dest1 SELECT 'abc', 'xyz', '8675309'  WHERE src.key = 86; 
SELECT concat_ws('.',NULL)  FROM dest1 ;

The result is a empty  string "",but I think it should be return NULL .
