vc                  	varchar(7)          	None                
s                   	string              	None                

hive> select printf(c) from vc;
FAILED: SemanticException [Error 10016]: Line 1:14 Argument type mismatch 'c': Argument 1 of function PRINTF must be "string", but "char(5)" was found.

However, if the argument is string type, the query runs successfully.
