> The balancer maintains an internal mapping of tablet server pools and tablet server status. It's updated at a configurable interval, which was done initially as an optimization. Unfortunately it has the negative side effect of providing the assignment and balance operations with stale information about the tablet servers which leads to a constant shuffling of tablets. The configuration property and optimization needs to be removed to supply the assign/balance methods with the correct information every time.
