changes by other thread in iteration.
                 Key: HADOOP-9980

            Reporter: Junping Du

LightWeightGSet should have a volatile modification field (like: LightWeightHashSet or LightWeight)
that is used to detect updates while iterating so they can throw a ConcurrentModificationException.
