As you don't need a reducer, have you considered using the
DistributedExecutorService with a DistributedCallable for that?<br>

I wanted to execute an operation only once on every key, independend
how many nodes are owner of the entry. <br>
The DistCallable approach was my first solution, where I checked at
every node for every entry, if the current node is owner, before I
modified it.<br>
So using the Mapper was a much simpler solution.<br>
