> 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.
