             Summary: nvl(x, y) throws NPE if type x and type y doesn't match, 
rather than throwing the meaningful error
                 Key: HIVE-11596
                 URL: https://issues.apache.org/jira/browse/HIVE-11596
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.0.0
            Reporter: Aihua Xu
            Assignee: Aihua Xu


{noformat}
create table test(key string);
select nvl(key, true) from test;
{noformat}

The query above will throw NPE rather than the meaningful error "The first and 
seconds arguments of function NLV should have the same type".
