As far as I can see from ticket title reporter wants to disable rebalancing on per-node basis. So, some nodes would not load partitions from other nodes while others should load normally. Disabling partition map exchange will stop rebalancing all over the grid (however, I find this pretty useful feature in some cases and it probably deserves a separate ticket).
I would ask Alexey Goncharuk to elaborate a little bit and add some background for the ticket he filed. --Yakov
