> The problem is that data cache rebalancing happens during the test, that
> causes data blocks affinity calculation to be not reproducible: block that
> initially maps to 0-th node after some time maps to a different node.
> Suggested fix is to switch off automatic rebelancing, and do the rebalancing
> manually only once upon the test beginning.
