>          Components: Balancer
>    Affects Versions: 2.0.0

>
> When master start, it initialize StochasticLoadBalancer.
> {code}
> this.balancer.setClusterStatus(getClusterStatus());
> this.balancer.setMasterServices(this);
> {code}
> It first setClusterStatus(), then setMasterService(). But in setClusterStatus method,
it use master service which is not initialized. So it will throw NPE.
> {code}
> int tablesCount = isByTable ? services.getTableDescriptors().getAll().size() : 1;
> {code}
> It happens when set isByTable is ture.
