It's even worse than just the missing package name.
When you create a jar, its root is supposed to be the root of your package tree.
So a class "com.foo.Bar" has to be in "com/foo/Bar.class" when you run
jar tf on the jarfile. If it's in "home/me/src/com/foo/Bar.class" or
just in "Bar.class" or
Looks like you need to learn a bit about how java package works. The path
for the class file needs to be
/home/huyong/test/*myudfs*/UPPER.class
Or remove the first line in your UDF code "package myudfs;" and redo
everything you did, it will work.

In this path, it has already contained UPPER.class and UPPER.java. And the
myudfs.jar is also in the path. But it did not work. By the way, my Pig
version is 0.8.1. Is there something, for example, classpath I have to set
up in the Pig configuration?

You need to have your class file in this path
/home/huyong/test/myudfs/UPPER.class
since it's in myudfs directory.

I tried your command and then it shows me as following:
/home/huyong/test/UPPER.class
/home/huyong/test/UPPER.java

This usually hapens when you aren't registering what you think you are
registering.
try `jar tf /home/huyong/test/myudfs.jar | grep UPPER` and see if you
get anything.

Hi,
package myudfs;
import java.io.IOException;
import org.apache.pig.EvalFunc;
import org.apache.pig.data.Tuple;
import org.apache.pig.impl.util.*;
public class UPPER extends EvalFunc
{
public String exec(Tuple input) throws IOException {
if (input == null || input.size() == 0)
Can you paste the content of the UDF?

Hello,
I just tried the example from the pig udf manual step by step. But I got the
error information. Can anyone tell me how to solve it?
