Description

Hive UDF doesn't get the right evaluate method if there is variable parameter in the method of evaluate.
For example:
public class TestUdf extends UDF {
public String evaluate(String a, String b) throws ParseException

{ return a + ":" + b; }

public String evaluate(String a, String... b) throws ParseException

{ return b[0] + ":" + a; }

}

the udf may get the wrong result
