hello,i want to use  udf to Resolve IP address，a local file is need.i want to create a new static object,but its error when run the sql.

if you cant understand,please check the javafile....thanks

 

//我想用udf函数来解析ip地址，需要引用一个本体文件来创建一个实例对象City，但是定义成全局变量会出错，请问该怎么写。

create temporary function IpCityName as 'udf.IpCityName' 可以成功，但是运行时候会报错。
