> Enable table doesn't assign out replicas keeping availability in mind, if the
> replicas were unassigned before the table was disabled. For example, when a
> snapshot is restored and then the table is enabled, the replicas are unevenly
> assigned. The reason for this is that the the enable table invokes
> randomAssign that assigns one region at a time. Since the master doesn't have
> any information about the unassigned replicas, the calls to randomAssign
> can't do any availability checks.
