Description

Usually, the hive udf we write comes with multiple evaluate methods to pass different numbers of parameters, but this udf will report the following error when registered in Doris:

A simple example is that a udf has the following two evaluate methods:

public String evaluate(String ip, String test) {
        return "good";
    }

public int evaluate(String ip, int test) {
        return 1;
    }

ERROR 1105 (HY000): errCode = 2, detailMessage = UDF class 'com.xxx.uu.hive.udf.Query' has multiple methods with name 'evaluate'
