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

                 Key: HIVE-1184

          Issue Type: Bug
    Affects Versions: 0.6.0

Depending on the order of expressions, the error message for a expression not 
in group key is not displayed; instead it is null.

{code}
hive> select concat(value, concat(value)) from src group by concat(value);
FAILED: Error in semantic analysis: null

hive> select concat(concat(value), value) from src group by concat(value);
FAILED: Error in semantic analysis: line 1:29 Expression Not In Group By Key 
value
