> Non-collocated IgniteSet shows multiple instances of the same objects when populated from different nodes.
> This code, when run twice on different nodes, results in more than 10 elements in set:
> {code:java}
> CollectionConfiguration setCfg = new CollectionConfiguration();
> setCfg.setCacheMode(PARTITIONED);
> IgniteSet<Integer> set = ignite.set("set", setCfg);
> System.out.println("Set size before init: " + set.size());
> for (int j = 0; j < 10; j++) {
>     set.add(j);
>     System.out.println(new ArrayList<>(set));
> }
> System.out.println("Set size after init: " + set.size());
> {code}
> Collocated set seems to work as expected. Populating from one node also doesn't create duplicates.
