How to write an UDF to pass Two parameters to a UDF Filter function.........

[Ramana Venkata]

Hi
 I want to create UDF which compares a tuple with a string value like this.

public class IsEqual extends FilterFunc {
    public Boolean exec(Tuple input,String str) throws IOException {
  // binary compary of AND is performed here;
 // if result of AND is not zero it will return true;
 return true;
}


is it possible with pig UDF ??;

Actually i want to compare two binary type data with AND operation as fallows

Table data is

ramana      1010101
krishna      1000010
venkata     1101010
......
load 'data' as name,category using PigStorate("\t");
cameusers = filter data  by  IsEqual(category,"1000010");
store cameusers;
-----------------------------------
result i am expected is ...............
krishna      1000010


Is there any other solution for this operation without UDF? can we
compare category column with binary data?


Please give responce..


thanks
