Sergey Shelukhin created HBASE-10794:
----------------------------------------

             Summary: multi-get should handle missing replica location from cache
                 Key: HBASE-10794
                 URL: https://issues.apache.org/jira/browse/HBASE-10794
             Project: HBase
          Issue Type: Improvement
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin
             Fix For: hbase-10070


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.
