Actually, there's no binary type in Pig. If you do not specify the type in
load statement, the default type is byte array. I'm afraid you have to
write a UDF to do the binary comparison. In the UDF, you should first
convert the byte array to binary and then compare the two binaries.

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

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..
