org.infinispan.distribution.ch.DefaultConsistentHashFactory.updateMembers()
Leavers are removed and segments without owners are assigned new owners. Joiners might get some of the un-owned segments but otherwise they are not taken into account (that should happen during a rebalance). @param baseCH An existing consistent hash instance, should not be {@code null} @param actualMembers A list of addresses representing the new cache members. @return

      members2.add(G);


      // create CHes
      DefaultConsistentHashFactory chf = new DefaultConsistentHashFactory();
      DefaultConsistentHash ch1 = chf.create(new MurmurHash3(), 2, numSegments, members1);
      DefaultConsistentHash ch2 = chf.updateMembers(ch1, members2);   //todo [anistor] it seems that address 6 is not used for un-owned segments
