Description

The MonitoredUDF feature doesn't work. When a UDF is annotated with it, job setup fails with an internal error. The stack is long, but the salient line appears to be:

Caused by: java.io.IOException: Serialization error: org.apache.pig.backend.hadoop.executionengine.physicalLayer.util.MonitoredUDFExecutor

I think making this class implement Serializable would solve the issue.
