Description

Some pieces of code related to the ordering of cache groups for the rebalance procedure can be removed. These parts of the code have been written to support Ignite under java 7 and no more actual.

E.g.

for (Map.Entry<Integer, GridDhtPreloaderAssignments> e : assignsMap.entrySet()) {
    int grpId = e.getKey();
    CacheGroupContext grp = cctx.cache().cacheGroup(grpId);
    CacheRebalanceOrder order = new CacheRebalanceOrder(
        grp.config().getRebalanceOrder(),
        grp.config().getRebalanceMode());
    if (orderMap.get(order) == null)
        orderMap.put(order, new ArrayList<Integer>(size));
    orderMap.get(order).add(grpId);
}
