> Currently the way cache works is that the meta row is stored together for all replicas
of a region, so if some replicas are in recovery, getting locations for a region will still
go to cache only and return null locations for these. Multi-get currently ignores such replicas.
It should instead try to get location again from meta if any replica is null.
