BaseScanner gets stale HRegionInfo in some race cases
-----------------------------------------------------

                 Key: HBASE-2927
                 URL: https://issues.apache.org/jira/browse/HBASE-2927
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.89.20100621, 0.20.6
            Reporter: Jean-Daniel Cryans
            Assignee: Jean-Daniel Cryans
            Priority: Critical
             Fix For: 0.20.7, 0.90.0


This issue is a branch of HBASE-2812, as it is a specific fix for disabling tables in some
situations. The issue is that the BaseScanner can get a stale HRI by the time it checks if
the region is OFFLINE, and even in trunk where we do a double checkAssigned there is no way
for us to tell if the region was offlined in the mean time.
