----------------------------------------------------------------------
I found out the reason for the problem. As I see, rebalancing can change
primary node with near cache when new client nodes appear. I'm not sure this is
a valid behaver, but this is what really happens (I have checked it).
So adding a call for *awaitPartitionMapExchange* can fix the problem. I will
double check this solution (locally and on TC), prepare PR and update status of
the issue when done.
