UDF registration does not work for nested classes
-------------------------------------------------
Key: PIG-2111
URL: https://issues.apache.org/jira/browse/PIG-2111
Project: Pig
Issue Type: Bug
Reporter: Gianmarco De Francisci Morales
Using nested classes as below does not work with the register command.
{code}
package mypackage
public class URLFuncs {
public static class MyEvalFunc extends EvalFunc<String> {
@Override
public String exec(Tuple input) throws IOException {
if (input == null || input.size() == 0)
return null;
try {
Object value = input.get(0);
if (!(value instanceof String))
throw new IOException("Cannot convert a " +
DataType.findTypeName(value));
String url = (String) value;
return url.toUpperCase();
} catch (ExecException ee) {
throw new IOException("Caught exception processing input row ", ee);
}
}
}
{code}
The error is as follows:
{code}
