Sunitha Muralidharan commented on PIG-2880:
-------------------------------------------
Can we define a new UDF as follows
package pigudf;
import java.io.IOException;
import org.apache.pig.EvalFunc;
import org.apache.pig.data.Tuple;
public class CharAt extends EvalFunc<String> {
@Override
public String exec(Tuple input) throws IOException {
String str=(String) input.get(0);//string input
int index=(Integer) input.get(1);//index
return str.charAt(index)+"";
}
}
> Pig current releases lack a UDF charAt.This UDF returns the char value at the
> specified index.
