    There are many functions in Drill which accept VARCHAR only and not VAR16CHAR. Why not
convert the Hive UDF return type to VARCHAR when the Hive return type is String? That way
we don't have to deal with many Drill UDFs that don't accept VAR16CHAR as input yet. For now
this case works fine, but the output of Hive UDF is given as input to some other function
(ex. LIKE), it wont work we don't have an implementation of LIKE for VAR16Char input?
