    Description

      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.
