> 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.
