OK. I did take a look at them. So once I have an accumulater for a HashSet, how can I check if a particular key is already present in the HashSet accumulator? I don't see any .contains method there. My requirement is that I need to keep accumulating the keys in the HashSet across all the tasks in various nodes and use it to do a check if the key is already present in the HashSet.
