> Looks like the following scenario can break data consistency after
> rebalancing:
> - start and activate the cluster of three server nodes
> - create a cache with two backups and fill initial data into it
> - stop one server node and upload additional data to the cache in order to
> trigger historical rebalance after the node returns to the cluster
> - restart the node. make sure that historical rebalancing is started from
> two other nodes.
> - before rebalancing is completed a new client node should be started and
> joined the cluster. this leads to clean up partition update counters on
> server nodes, i.e. _GridDhtPartitionTopologyImpl#cntrMap_. ( * )
> - historical rebalancing from one node fails.
> - in that case, rebalancing is reassigned and starting node tries to
> rebalance missed partitions from another node.
> unfortunately, update counters for historical rebalance cannot be properly
> calculated due to ( * )
