> I can get the information from GenericUDAFParameterInfo, to judge if user inputs DISTINCT keyword.
> But I want to judge in the iterate method, could anyone get me a hint??
> In GenericUDAFCount.java(line 125)，a boolean variable *countAllColumns* is used to see whether user input *.  However, it doesn't work :(
