Subject: Re: can i define an udf which can process more than one argument?
Hi Chris,
Of course it is possible to write UDF with as many parameters as you want, even
with
i find that UDF can only process one argument like
public long evaluate(String ip) {
}
can i define a udf like COALESCE(T v1, T v2, …) or if(boolean testCondition,
T valueTrue, T valueFalseOrNull)?
