Keith Turner created ACCUMULO-1246:
--------------------------------------

             Summary: Metadata cache should reject tablets with mutiple locations
                 Key: ACCUMULO-1246
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1246
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.4.0
            Reporter: Keith Turner
            Assignee: Keith Turner
             Fix For: 1.5.0


A tablet being assigned to multiple locations is a condition that indicates a bug in Accumulo.  If this should happen the client side code that caches tablet location from the metadata table will currently just take one of the locations.  If a tablet has multiple locations, then the client code should fail.  Proceeding when a tablet has multiple location clould result in silent data loss or reading stale and/or incomplete data.
