Don't ignore corrupt StoreFiles when opening a region
-----------------------------------------------------

                 Key: HBASE-4778
                 URL: https://issues.apache.org/jira/browse/HBASE-4778
             Project: HBase
          Issue Type: Bug
            Reporter: Nicolas Spiegelberg
            Assignee: Mikhail Bautin
             Fix For: 0.94.0


We used to ignore StoreFiles that failed to open, which led to a situation when 
only a subset of regions was opened, and HBase did not return results to 
clients for the affected set of keys. This change makes sure we propagate 
IOExceptions coming from an attempt to open a StoreFile all the way up to 
HRegionServer.openRegion, where it will lead to a failure to open the whole 
region. This way we can avoid returning corrupt data to the application.
