The reason you saw that is because when you provide evaluate() method, you
are "OK", make sense?

I have implemented a simple udf for test.
public class test extends UDF {
private Text t;
}
}
And the test query: select test() from AnyTable;
I got
initialization
initialization
initialization
...
I have also implemented a similar GenericUDF, and got similar result.
What' wrong with my code?

Your UDF object will only initialized once per map or reducer.
When you said your UDF object being initialized for each row, why do you think
so? Do you have log to make you think that way?
If OK, please provide more information, so we can help you, like your example
code, log etc
